I come across this problem. I need help to solve this problem
Integral ( (ax^3) / ((e^(bx)) - 1) dx
For general values of a and b, it can't be done using a finite number of elementary functions. See below what happens when a = b = 1, for example. Perhaps it's meant to be a definite integral ....?

Pretty sure of it.
Mostly times I've seen people tryin' to compute (like if always would exist) an antiderivative for the function, but they don't realize the importance of the integration limits.
