Power transmitted along the string by a sinewave is given by P = μ*ω^2*A^2*v*cos^2 (ωt - kx). Find expression for average power over t = 0 to t = T.
[ω = 2π/T]
How to do it? Please explain all the steps.

I assmume it wants this
Let $\displaystyle P\left(\mu,\omega,A,v,t,k,x\right)$ represent that ugly thing, then the average on $\displaystyle t=0\to{t=T}$ would be
$\displaystyle P\left(\mu,\omega,A,v,t,k,x\right)_{\text{average} }=\frac{1}{T}\int_0^{T}P\left(\mu,\omega,A,v,t,k,x \right)dt$
