Sinx and cosx functions

  1. Apr 2, 2007 #1
    What differences is there between a sinx and cosx function?
    Do they both use this equation?
    y=Asin(BX+C)+D

    That's too in depth for me.
    I just wanted to know the difference between
    y=sinx and y=cosx when graphed.

    Maybe cristo just missed it, but Ry122 is actually right, cosine can also be expressed in that form of asin(bx+c) + d.

    This happens because sin (90degrees-x)= cos x.

    So in answer to your original question, the difference when graphed between sin x and cos x is that the cos graph is the same as sins, moved back 90 degrees to the left.
