Does the Gamma Function have an Inverse? (Is there an "arc-gamma" function?)
Where $\Gamma(x) = y... \Gamma^{-1}(y) = x\ (arc\Gamma(y)=x)$.
I've searched and found something called DiGamma Function, but when I substituted it didn't seem to be an inverse ("arc") but something else. I am not yet developed enough to understand haha...
Edit, I'd like to draw special attention to the comment below by u/G Cab
