How to solve digamma function
WebThe gamma function is an important special function in mathematics. Its particular values can be expressed in closed form for integer and half-integer arguments, but no simple expressions are known for the values at rational points in general. 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.
