i still don't really understand how to figure out the parametric equations for a circle-- it's something involving sines and cosines i think? if anyone knows what i'm talking about/ can explain it to me, that would be great. thanks.

The equation for x is x=r*cos(t)+a and for y is y=r*sin(t)+b, where r is the radius, a is the horizontal shift, and b is the vertical shift.
