How to solve digamma function
Did you know?
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.

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. So, I think that numerical calculus is required : There are several methods for numerical solving of non-linear equations, based on more or less sophisticated iterative process. 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.
WebPolyGamma [z] is the logarithmic derivative of the gamma function, given by . PolyGamma [n, z] is given for positive integer by . For arbitrary complex n, the polygamma function is defined by fractional calculus analytic continuation. PolyGamma [z] and PolyGamma [n, z] are meromorphic functions of z with no branch cut discontinuities.
