I need to draw a sine curve (from x = 0 to 2pi) as part of a DrawingVisual and would like to use WPF's basic path capabilities to get a smooth curve. Probably I need some sort of bezier curve for that. Unfortunately I don't even know how they work. (Just that they can "pull" the line towards a control point somehow.)
Can somebody tell me what coordinates I should use to make it look right?
I could apply a ScaleTransform if I want to stretch it a little, so the normal form would be fine.
A thread in the MSDN forums just brought me in the middle of a formula mess in Wikipedia's scientific depths. I haven't studied maths so that's not much use to me.
Nevermind, I played a while with Kaxaml and found this pretty neat. It's probably a bit stretched already, but it makes the plot more recognisable.

The first Path (grey) shows the control points used and how they are on the same horizontal offset; the second Path (red, bold) shows the final bezier curve.
This is how it looks like:
