[SOLVED] Application of calculus for finding expression?
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.
Is everything assumed to be a constant that isn't t? In other words what is the variable as to which we are supposed to be differentiating in respect to?
I dont know for sure myself. But since the question asks for expression over t= 0 and t = T, i think w.r.t t. I think we have to assume the others to be a constant.

I assmume it wants this
Let represent that ugly thing, then the average on would be
