Wave function at origin on transverse wave

  1. Feb 18, 2013 #1
    1. The problem statement, all variables and given/known data
    You have the simple harmonic equation for a transverse wave which is y(x,t)=Acos(10∏t+5x), what is the wave function at the origin

    3. The attempt at a solution
    By "at the origin" does it mean where x=0 and t=0. Because it that case y=Acos0 and therefore y=A. Is that right???

    I would interpret it to mean to let x = 0 and let t vary, but your interpretation may also be what was meant.

    I am sure the question wants you take it as when x = 0 and t various
    so y(0,t)=Acos(10∏t) = wave function at origin.

    Thanks guys, I talked to my teacher and i can safely conclude the answer is y(0,t)=Acos(10∏t)
