Starting from zero amplitude, the cosine curve repeats itself between
- -180 and 180 degree.
- -90 and 270 degrees.
- 0 and 360 degree.
piesoup asking:
What is meant by 'repeats itself'?
Thanks

It repeats itself every 360 (2pi) degrees starting from -90 (-pi/2) degrees.

ok, but why 0 and 360 isn't correct?
