The superposition of two harmonic waves:(adsbygoogle = window.adsbygoogle || []).push({});

u1 = B * sin( a1(r) )

u2 = B * sin( a2(r) )

results in a sinusoidal wave of the form:

uint = Bint * sin( a3(r) )

Find a3 and Bint

I'm not sure what to do. I can't think of any way to get it into that "form". http://scienceworld.wolfram.com/physics/Interference.html (5) on that link gives the form I would expect.

I think the "int" subscript is talking about intensity, and I'm not sure but I don't think either u1 or u2 depend on time.

Can anyone help?
