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. WebUsing the defined relation for the digamma function, namely, Γ ( x) ψ ( x) = Γ ′ ( x) then the digamma relation is ψ ( x + 1) = ψ ( x) + 1 x. Applying differentiation again leads to the following trigamma relation: ψ ′ ( x + 1) = ψ ′ ( x) − 1 x 2. Share Cite Follow answered Nov 12, 2024 at 20:58 Leucippus 25.3k 153 40 86 Add a comment
