## Main Question or Discussion Point

Hi

I Googled http://mathworld.wolfram.com/Trochoid.html" [Broken] but wasn't able to find formulas for the instantaneous velocity of a point on trochoid curves. Does anyone know of an online reference (or know how to find the velocity)

I can get rough estimates by calculating the distance between two "ticks" on a trochoid curve but I want to get exact values if possible.

Thanks for any help
