Hi Jonathan,

The half cycle would be written:
sqrt(1-x^2)
since in a circle x²+y²=1

Then depending on how you want to use it, you'd have to figure out a way to have the lower portion.
See attached patch with a [phasor~]

Hope this helps.

Cheers
Pierre-Olivier

Hi list,

If I take a circle, cut it in half horizontally, then move the bottom half r*2 units to the right, what is the waveform that results?
