Homework Statement


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


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)
