Need Help Solving a 2nd order Differential Equation

I need to write a computer program in MATLAB to solve the following 2nd order differential equation:
     y" + (1/r)y' + (200/80) = 0
I can't remember which method I'm supposed to use to get an equation for y(r)? Once I know the method... I'm sure I can implement it.
Thanks for your time

You can implement Java code in MATLAB??? Is that what you're saying? If so, please tell me how because that would be helpful to me!

    Hi everybody, I am in Turkey on a long assignment, I need help solving a big problem on my macbook pro os 10.9.3. The other week my wife visited some website and now we have a redirect virus of some sort, and every other time when we click on a link or anywhere on the page we are redirected to this casino web site, https://casino.7bets10.com/tr/?from=hy9yKXD43jSC-8Oxbw4femNd7ZgqdRLk-dHJpeG9uaXR l. Its the same whether on Chrome or Safari. Does anyone have a solution, thank you!

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
    Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
    Here's a summary of what you need to do, if you choose to proceed:
    Copy a line of text in this window to the Clipboard.
    Paste into the window of another application.
    Wait for the test to run. It usually takes a few minutes.
    Paste the results, which will have been copied automatically, back into a reply on this page.
    The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
    Triple-click anywhere in the line of text below on this page to select it:

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal application in any of the following ways:
    Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
    8. If you see an error message in the Terminal window such as "syntax error," enter
    exec bash
    and press return. Then paste the script again.
    9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
    [Process completed]
    to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
    11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

    I updated the new IOS 4.3.3 on my IPad, since then i Am having trouble accesesing any App. What happens is i cant enter it or other wise it closes as soon as i enter it...i need help solving tris inconvenient.

    I have the same problem and I haven't solved it yet. On Friday I plugged in my iPad to my work computer after not having done so for quite a while. Today I went onto the work computer and discovered I had not updated iTunes before plugging in the iPad (and which I cannot do without an administrator password). I guess I will update iTunes and try again when I can get the guy to show up with the password. I hope that works. The reset idea does not work on mine.
    Was your iiTunes updated before you tried? Have you found any solution yet? Mail and some internet apps still work but games, notes applications, spreadsheets etc. just begin to open and close immediately.
    If anybody has answers I'd love to get some clues.

  • 2nd Order Differential Problems

    Hey I'm creating a second order differential solver and I'm using the differential solver VI's that come with the package. However, the solver won't do 2nd Order ODE's that are critically damped. Does anyone know what this problem is and how I can remedy it? I put a copy of my program here to show you the problem. For an example of a critically damped equation, input 4 in both "dy/dt" and "y". Thanks.

    Hey Jay,
    The modification I made is not that complex, so I'll explain what I did step by step. Before I go through the process, I should offer a disclaimer.
    When modifying ODE Linear nth Order Numeric VI, you may want to save a local copy for yourself. This will ensure that the shipping version of the VI is not altered. If you modify the shipping version, then leave it that way, you may run into errors when you try to use the VI in the future.
    Also remember to verify the results of the critically damped case. Since the VI is not designed for ODE's with repeated eigenvalues, it's possible that you could be getting incorrect results after the modification. With that said, here's the procedure I used to modify the VI so that it runs even with repea
    ted eigenvalues.
    1. The modification I made was to the ODE Linear nth Order Numeric.vi. You can access the VI's code by simply double clicking on it from your VI.
    2. The change I made is located in the red circle on the bitmap I sent you.
    3. Look for the "Multiple Roots.vi", the gray one with a sigma in the upper left corner and some arrows and dots on it. The output of this VI is a boolean, and it is connected to a not gate.
    4. Delete the wire from the output of the "Multiple Roots.vi" to the not gate.
    5. Right click the input port of the not gate and create a constant.
    6. Make sure that the boolean constant connected to the not gate is false.
    This is what I did to ensure that the VI will run regardless of the eigenvalues. Please be aware of the issues I addressed above. Otherwise, good luck!

  • I'm a Noob, and need help solving a backup issue.

    I previously had an Alienware PC with a 1TB harddrive.  I backed up to the cloud using Carbonite.
    I decided to get a new laptop and got a MacBook Pro with Retina.  It only has 128GB harddrive.  My plan was to use a 2TB external harddrive and back up both using Carbonite.  Well, turns out Carbonite only does external harddrive backup with PC's not Macs.  So, I need help.
    I have way more files than can fit on my laptop that need to be accessed and backed up on a regular basis, so it would seem time machine isn't the solution.
    What do you do? or would you recommend?  What is the best way for someone like me who wants continual access to and backup of a large amount of data?  Are there any good cloud based solutions you would recommend?
    I appreciate your help!

  • Need help solving my FCP OS9.2 update problem

    Hey all you maciacs. I just bought my second mac yesterday (used of course) and it had OS 9.1 on it. Well I was trying to install FCP on there under OS 9.2 and I went to upgrade and it kept saying system error 10. So I kept trying to figure things out and go on the internet and download OS 10 something. Now I was able to install FCP on my G3 (it's used as well) but I don't get real time effects.
    So long story short I stayed up about 6 hours trying to figure this thing out then it gets stuck on the internet and I restart but it doesn't reboot all the way a question mark and the half face blinks on and off.
    I need help is there a way to get the G3 to be at 500 MHZ speed to give me those real time effects or would it be cheaper to get this thing going on this G4? Who out there knows and cares to help a brother struggling?
    Is it u?

    Hi, finallyamacman -
    OK, it's a G4 (AGP) model.
    I just bought my second mac yesterday (used of course) and it had OS 9.1 on it. Well I was trying to install FCP on there under OS 9.2...
    Does it have OS 9.1, or OS 9.2.1 or OS 9.2.2? If you updated it from OS 9.1, did you use a CD or a download update?
    What OS 9 Install CDs do you have available? Specifically, retail ones - all retail OS 9 Install CDs have a white label with a large gold 9.
    So I kept trying to figure things out and go on the internet and download OS 10 something.
    You can not upgrade OS 9 (any version) to OSX by using download updates - they just don't exist. To get OSX on that machine, an initial Install of OSX must be done using a retail package disk set, then that can be upgraded within its base version using download updaters.
    ...it doesn't reboot all the way a question mark and the half face blinks on and off.
    That indicates the machine can not find a usable OS from which to boot.
    This can result from many events - the OS on the hard drive has become damaged in some way; one or more of its critical components has been moved out of the System Folder, such as the Extensions folder; there is directory corruption; or something else.
    It can also result on some models from the internal battery being too weak or dead. Since it is a used machine, it is reasonable to assume it was left sitting unplugged for a while before you got it; this will drain the battery much more rapidly than would happen during normal usage. I'd recommend replacing the battery - you can get one at places like RadioShack for about US$17, cheaper on-line.

  • Need help: playing songs in order, strangewindow message, upgrading I-Tunes

    I have 2 situations I hope someone can help me with:
    1: PLAYING SONGS IN ORDER; WINDOW MESSAGE
    I have CDs of music that when I load them onto my pc laptop the song names don’t come up—each song lists as “track 01” “track 02” etc.
    When I try to play the album thru I-Tunes on my laptop, the songs won’t play in order. i.e. ALL the “track 02”s will play before going to “track 03,” then ALL the “track 03”s will play, etc. So I made a playlist of each CD.
    Now when I try to play the Playlist, I get a window message that says, “The song “Track 01” could not be used because the original file could not be found. Would you like to locate it?” I can choose ‘yes’ or ‘cancel.’ YES takes me to folder selections. I find the song and click on it and then it plays.
    There must be an easier way. I don’t want to search for each song one at a time in order to play an entire CD in order.
    2: UPGRADE
    I need to upgrade. I have I-TUNES 7.0.2. I went online to apple.com and couldn’t find any upgrade option, so I clicked on “download I-tunes”. I got a window that says “download complete.” But how do I tell if it’s really installed? Where do I go on my computer to see what version number it shows?
    Any help is appreciated,
    Carolyn in Las Vegas

    2. Help->About iTunes
    1. You have done something that has confused iTunes about the location of the files in its library. Without knowing what happened, it's hard to make a specific recommendation, but if you moved your files around manually, move them back, and then, if you want to change the location, do it only by setting it in iTunes preferences and then using Consolidate Library.

  • Major iPod Problems, Need Help Solving

    One day I was casually syncing my iPod video with my computer to get a few new songs uploaded onto it.
    Suddenly, the iPod freezes up, shuts itself off, restarts, and magically it has forgotten everything and pretends it is a brand new iPod.
    No problem, I think, believing it will just need to load the songs again and everything will be fine.
    However, this is not the case.
    The iPod would then continue to load all the songs, shut down after loading them, restart and again pretend it is brand new and lad all the songs again.
    This continues to happen again and again.
    I try to update my iPod, figuring it may just be a version error or somesuch nonsense. The updater refuses to work and actually causes my iPod to crash, saying it has a diskwrite error.
    It refuses to "System Restore" on my computer, so I run the "System Restore" on another window computer that I own. And it runs just fine, making the iPod load songs once more.
    And I think, problem solved!
    However, again, this is not the case.
    I load it once, everything goes fine.
    The nxt day, after buying more songs, I try to upload and after the upload, the iPod shut off, restarts, and pretends to be new once more.
    I go through the "System Restore" process again, but afterwards, the iPod all out refuses to upload my music fully, shutting off about halfway through the process each time.
    And now whenever it is plugged into my computer, windows says it is unreadable and must be reformatted, so I run the updater and it says that there is an "iPod manager internal error" which could basically be another language considering my only basic knowledge of computers.
    Is there any way to repair my iPod at home? Or must it be sent in to Apple?

    GREAT NEWS!
    Last night, through some very thorough digging in the
    "Search Discussions", I found the answer and now my
    iPod is running perfect once more!
    Thank you very much for your help b noir. Without
    you, and many others on this board who had their
    problems solved by equally helpful people, I would
    still be digging through Apple's support section to
    no avail.

  • Consistant Brush Lag in Photoshop, need help solving

    I know there have been others who've had this problem in the past, and I have researched and looked through various possible causes and finding nothing.
    I'm using a laptop with pretty good standard graphics and memory, more than what I was using specs-wise compared to my previous desktop. I use them for my graphics work and digital art, but photoshop has been acting inappropriately laggy concerning brushes and pencilstrokes! Everything else tends to be fine. I have tried messing with the photoshop pref file, reinstalling wacom drivers (compatible for Win7 32bit), changing the win7 desktop Aero background, managing things running in memory, even looked for updates to the GPU which apparently said it was up to date after i installed it!
    This has been bugging me and I use Photoshop7 and PS CS2 for my digital art and design and it bugs me that I cannot use the brushes or pencils and related tools. The strokes do not catch up with the motion of my pen and instead either dissappear or create stiff lines, occasionally loosening up. But this needs to be solved so I can know what to do incase of future times.
    My stats are:
    Toshiba Satelite Laptop
    AMD Single Core 2ghz Processor
    2gig RAM Memory
    ATI Radeon 3100 256mb GPU integrated
    250gb HDD
    Help will be greatly appreciated! Also want to note that it is PS and Gimp that I see this only happening in, but other art programs run like butter on my laptop.

    First of all, thank you so much for taking the time to try to help out. It
    is much appreciated.
    The two things that first come to mind are: I have many friends in the
    industry who paint solely in Photoshop and do just fine. My computer is
    technically "old," but the specs are still just fine—even the graphics card
    is the exact same one that is in the new Cintiq Companions (the all-in-one
    computer/cintiq machines).
    And, more so, I was painting on it for a few weeks without noticing
    anything. A part of me wonders, did I just not notice it until it became
    dramatically worse?
    I do remember painting fur, which requires making tons of small brush
    strokes over an extended period of time, and I don't remember there being
    any lag.
    By the way, I forgot to mention: I've even tried going into the Performance
    preferences and disabling the graphics card altogether. No luck. Still an
    issue.
    As far as painting at 100%: I do notice an amount of improvement. The one
    brush stamp, or space, whatever you call it, issue only happened on the
    first brush stroke (every time) and then just once otherwise. The lag was
    tremendous—and I compared it to Painter's performance, which had no issues
    whatsoever.
    I am really hoping to be able to rely on Photoshop more and more, as its
    tools for other aspects of image manipulation are far more robust than
    Painter's. And the working compatibility with Adobe InDesign, Flash, and
    Adobe Media Encoder are sooooooo useful for speeding up the workflow.
    Hopefully we can find out what's going wrong.
    I'm truly baffled on this one.

    Hi tavassoli68,
    Welcome to the Best Buy forum, and thank you for posting.
    You will most definitely need an order number if you want to check the status of your order.  I pulled up your purchase history using the email address you registered with the forum, but could not find a purchase for a Samsung washer and dryer.  I will need some additional information from you, so I will be sending you a private message.  You can check your private messages by logging into the forum and clicking on the little yellow envelope icon at the top of the page.
    I hope you have a fantastic day!

  • Need help in cancelling a order

    Hey, I ordered a 15" MBP yesterday morning, but have now realised that it would make much more sense to order the 17" one instead. The problem is that despite my order page stating that it will not ship for 3 days and having an estimated delivery date of two weeks from now (23rd) it will not let me cancel the order as it says they have been prepared for shipment. I ordered a slightly upgraded HD, but two weeks! I really don't want to wait for it to come and then have to send it back. Is there anything I can do?

    Glad to see you're getting a new MBP... However, while you are trying to determine what you need to do to change your order, have you seen the MBP 15 and MBP 17 in person?
    There is a big difference, and when I recently purchased mine, I went with the 15 as the 17 would be very bulky to handle normally.. However if you are stationary then you'll do fine.
    Additionaly one other difference as you may know already is that the MBP 15 has a SD card slot, where the MBP 17 does not instead it has the express bus port for add-on devices.
    I'm just trying to help, as I went for the high end MBP 15 and decided to save a few hundred by doing such... I can't complain about my decision and from having 17" PC based laptops, I like the portability factor of the 15" so much more.
    Hope that kind of helps, but if your set you will need to call apple to corect..

  • Need help solving Error 3005 using activex server and automation open.

    Hi,
    I am trying to use a master vi to call a slave vi by using the activex server option. The steps i have taken are:
    1. In the slave vi, go to advanced tab in build options and check enable activex server.
    2. After building the .exe go to the command prompt and type the path to the .exe followed by /RegServer. Ex: C:\slavevi\applicatoin.exe /RegServer. This will add it to the activex plugin list.
    2.a restart labview if it was open.
    3. In the master vi use automation open, create a constant for the automation refnum and right click it. Select browse. Browse to the name you chose in the enable activex server field from step 1. Choose “show creatable objects only” and pick the _application one.
     4. use an invoke node and connect automation open to it. Choose getVIReference. This will drill down to the actual vi you want to control.
    5. The path will be the install path + the vi name. Ex: \slavevi.exe\mainviname.vi.
    These steps actually worked on the machine that I built the vis on but if I build the exes and transfer them to another computer I get error 3005 when it tries to open the slave.exe program. In each instance the master and slave vis are both local (not trying to go through a network or anything). I have registered the slave.exe and .tlb file on the new computer, rebooted etc and nothing seems to work. I also tried running the master vi as source code but that didn't work.
    The master vi was originally built in labview 7.1 and the slave is built in LV 9.01 but I have since upgraded the master vi to 9.01 to try and resolve the problem.
    Is there something that happens during a build that needs to be replicated on the new computer?
    Thanks for any help.
