Sine wave

Hi, I'm trying to draw a sine wave, with a thickness of about 3.

When I draw it, the curve never comes out smooth, even with antialiasing turned on.

I've tried drawing lots of line segments, using ovals, and also polygons. but none of them come out smooth...
You can always see like a ladder effect along the curve close up.

Can anyone help me do this? Thanks very much.

Nevermind, I just used a cubic bezier curve, makes it look better, so I don't need the sinewave now. Thanks

Does a Bezier curve match a sine wave? Show us how.
