How to solve digamma function

WebThe digamma function is the first derivative of the logarithm of the gamma function: ψ ( x) = d d x ln Γ ( x) = Γ ( x) Γ ( x). Polygamma Function The polygamma function of the order k is the (k + 1) th derivative of the logarithm of the gamma function: ψ ( k) ( x) = d k + 1 d x k + 1 ln Γ ( x) = d k d x k ψ ( x).

WebNov 25, 2024 · The Digamma function is a further extension: ψ ( z) = Γ ′ ( z) Γ ( z) and can itself be extended with the Polygamma function: ψ m ( z) = d m d z m ψ ( z) All sources I have encountered that mention the Digamma (or Polygamma) denote it as above with the greek letter 'psi' ψ. This befuddles and confuses me. WebFrom this, we can find specific values of the digamma function easily; for example, putting s=0, s = 0, we get \psi (1)=-\gamma. ψ(1) = −γ. Also, by the integral representation of harmonic numbers, \psi (s+1) = -\gamma + H_s. ψ(s+ 1) = −γ + H s.
