How to solve digamma function
WebThe formula for Gamma Function Formula can be calculated by using the following steps: Step 1: Identify whether the input value is an integer or a real number. Step 2: If it is an integer, then we have to go with 1 st … 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
