Wave Power

So in my book, it derives the expression for power in a travelling transverse mechanical wave.

P= Sqrt[(mu)F].(omega)^2.(A)^2

It reduces this from: P=k^2.omega^2.F.A^2.(sin(kx-omega.t)^2

Where all symbols are the standard ones in dealing with waves.

Could someone please go thru how it got from 2 to 1? I can't see the logic. I'm sure its obviously just basic math I am overlooking, but there may be a misprint in the derivation.

Cheers!

Can you fix the equation in your threadd? I can't read the problem, sorry.

P=[Sqrt(uF)](w^2)(A^2)
