Intersect of three sinusoidal functions

  1. May 6, 2008 #1
    hi, is it possible to find the intersect of three different sinusoidal functions without using a graphing calculator?

    here are the three equations:

    y=sin (2pi/23)(x)
    y=sin (pi/14)(x)
    y=sin (2pi/33)(x)

    The hint given is that the intersect occurs when y=1

    What is x when sin(x) = 1?
