Homework Help: Simple Harmonic Motion/Wave Motion

  1. Sep 21, 2005 #1

    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

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