I ask somebody to do it, then he tells me the result. Or rather, my code
asks another part of my code to evaluate it at X the other part returns the
result.

As you probably have guessed, the function is too complex to find the
inverse of mathematically, so I have to use approximation. And I simply
asked for a fast way to do that.
