I = \int e^{5x} \sin^3(e^{5x}) \cos^6(e^{5x}) dx we make the substitution t = e^{5x} to obtain I = \int f(t)dt where f(t) = Then we make the substitution u = \cos(t) and obtain I = \int g(u)du where g(u) = Now you can calculate the value of the integral (in terms of x) which is I = +C where C is an arbitrary constant.
