WebNov 23, 2024 · If you take a look at the Gamma function, you will notice two things. First, it is definitely an increasing function,with respect to z. Second, when zis a natural number, Γ(z+1) = z! (I promise we’re going to prove this soon!) Therefore, we can expect the Gamma function to connect the factorial. WebSince the inverse function of the digamma is not related to a referenced special function, there is no hope to find the solution on a closed form.
