Sinusoidal graphs (y=sinx and y=cosx equations)

  1. Oct 2, 2006 #1
    i was wondering how you would find the amplitude, vertical translation, horizontal translation and the sinusoidal axis either from just an equation, like 1/2(y-7)=cos3(x-60), or from the graph if you are given one.

    Write it in the form y= and the items you want would be obvious.

    amplitude = 2, vertical (also axis) = 7, period = 2pi/3
