Digamma Integral Representation
I'm trying to figure out how the integral representation of the Digamma function works.
I understand that the Digamma function is the logarithmic derivative of the Gamma function. Therefore
then I would think
Anyway, the integral expression for the Digamma function is given by
How would I derive this formula?
Should I instead look at another representation of the Gamma function and work with that?
You have done a great job !
Your substitution is perfect (Clapping) !
We need to make a further substitution ,
