How to graph sin and cos function on grapher?

Question

Hello,
I am needing to graph this function on grapher, but can't (obviously, it's without the questinon mark). 
All I get is this and no graph. :
Can anybody tell me how to get the actual sin wave on the graph?
Thanks!

Here's how to animate a point along a graph. In this screenshot, we have the first function show the expected sine curve. The second function is a pair of values, defining x and y each as functions of "n" and then plotting the pair. Since x and y in this definition takes on one value at a time (and no range), you get a point. To animate the graph, you define "n" as a separate function (create a new function, delete the "y=" and replace with "n="). To make this a smooth evaluation of all points, click "n" to give it a value, and then press Option-Command-A to invoke "animation". You can then click the icon with checkmarks and two lines (to the far right seen here), and set the range for "n" along with subdivisions, or continuous values. You can then drag the slider to change the value for n, enter a specific value in the value box, or click the play button to animate back and forth.
Note that in this screen shot, to in part answer the original poster's question, I've defined "f(x)" as the function "sin(x)" and then to display the function, since grapher plots y as a function of x, I've set y=f(x) so this behavior can be drawn. Its redundant, but allows for the management of functions in some ways that might be useful. For instance, you could do a set of functions such as the following:
f(x)=x
g(x)=x^2
h(x)=x^3
...and then plot them all with y={f(x),g(x),h(x)}.
In this instance, since the graphs are all increased powers of x, you can follow this trend by plotting over a set of values:
set={1,2,3,4,5}
f(x)=x^set
This will plot x^1, x^2, x^3, x^4, x^5, etc...and you can also throw an "n" value in the set, then animate it, so some of the functions remain static while others are animated by the value of "n".
....the possibilities are vast.
