hey everyone,
in my never ending quest to find interesting maths based animations i created a trig function but dont understand it.
the function is y = sin(x) where x = x+k*sin(x). k has a starting value of 20 and x starts at 180 (or PI).
the function iterates once every frame.
have a look at the animation strange trig
when k is changed (using the buttons) to a multiple of 22 the the function becomes very stable, and i cant work out why.
