Line 7: ==Calculation== The digamma function, often denoted also ψ<sub>0</sub>(''x'') ~~or even~~, ψ<sup>0</sup>(''x'') or F (after the shape of the obsolete Greek letter Ϝ [[digamma]]), is related to the [[harmonic number]]s in that :<math>\psi(n) = H_{n-1}-\gamma</math> where ''H''<sub>''n''−1</sub> is the (''n''−1)th harmonic number, and γ is the well-known [[Euler-Mascheroni constant]].
