Hi,

I need to find the frequency, amplitude, and period for the motion of a particle whose distance s from the origin is the given function.

s= 2sin2tcos2t.

This is what I came up with, can someone please tell me if I am doing this correctly.

sin2t = 2sintcost

s = sin4t

A= 1
P= Pi/2
F= 2/Pi

Thanks.

Looks good to me. (Assuming that 2t is in radians.)
