Best ResponseYou've already chosen the best response.1Didn't you already do this ? you have a sin t that you want to rotate faster to make it rotate twice as fast, use sin(2t) (and cos(2t) ) and keep everything else the same.

Best ResponseYou've already chosen the best response.1as I remember, in the first part, the hoop has a diameter of 2, and a radius of 1 for the next part, I think you want a hoop with 1/2 the diameter, so its mark hits the floor twice as often. that means its radius will be 1/2 and its diameter 1
