Hi, I'm new here and new to Mathematica also.

So, I was defining two functions, s1 and s2. Both are the same functions but one was simplified after the integration and the other one wasn't.

So I calculate the inverse of these functions (and once they are the integral of the same function, I expect that the inverses would return the same values) and that is not happening.

I would like to understand why the Simplify cause the inverse equations to have different solutions.

I'm adding a notebook to demonstrate my question:

If anyone can help, I really would appreciate it Thank you very much in advance .
