Join 2 lines with Arc

Question

Anyone could give me a example to join 3 lines with Arc?
I´ve already tried to join using QuadCurveTo, but my lines were wrong.
Thanks,

Oh, so it is much simpler than I thought... :)
Here is a quick code to get you inspired:
var scene: Scene;
Stage
    title: "Forum Test"
    scene: scene = Scene
        width: 1000
        height: 100
        content:
            Button
                text: "Show wave"
                action: function (): Void
                    insert MakeWave() into scene.content;
function MakeWave(): Path
    println("Making a wave");
    var wave = Path { stroke: Color.LIGHTBLUE, strokeWidth: 8 }
    def radius = scene.height / 5;
    def high = radius;
    def low = scene.height - high;
    def len = (scene.height - 2 * radius) * Math.sqrt(2);
    def arcLen = 2 * radius / Math.sqrt(2);
    var xPos = radius;
    var yPos = low;
    insert MoveTo { x: xPos, y: yPos } into wave.elements;
    println("{xPos} - {len} - {scene.width - len - arcLen}");
    while (xPos < scene.width - len - arcLen)
        xPos += len;
        yPos = if (yPos == low) high else low;
        print("{yPos} - {xPos} ... ");
        insert
                LineTo { x: xPos, y: yPos }
                ArcTo
                    x: xPos + arcLen
                    y: yPos
                    radiusX: radius
                    radiusY: radius
                    sweepFlag: yPos == high
        } into wave.elements;
        xPos += arcLen;
        println(xPos);
    return wave;
}That's not a mathematical sinusoid but I think that's what you meant.
