Exactly, Sage doesn't recognize it. So, i'm completely stuck :S

Thanks for your answers!

I tried to use the mathematica_free algorithm. There is an additional problem: the constant b is indeed a function some variable y. It is of course a constant, but it is undetermined when integrating the function.

So, Sage returns:

NotImplementedError: Mathematica online integrator can only handle single letter variables.

Oh, I see, i didn't know the mathematica_free algorithm. If i understand correctly, Sage is taking the result from the online integrator, isn't it? The next question is if i can work further with that result. For example, evaluate it, etc.

In that case, i should stick to Mathematica, I guess...

Hello all,

I'm trying to get the integral with respect to x of the following expression:

(a / x + b(y) * x ^ c) ^ d,

where a,c,d are positive constants, and b is a function of some variable y.

I'm not sure what I'm doing wrong. Can you help me?

I got a solution in Mathematica (some hypergeometric function), but Mathematica is a software that I'm trying not to use anymore.
