Inverse incomplete gamma function and its application

WebThe derivatives of the log‐gamma function and the inverses of the regularized incomplete gamma functions , and with respect to the variables , , and have more complicated representations by the formulas: The derivative of the exponential integral by its parameter can be represented in terms of the regularized hypergeometric function : WebFrom Eq. 1.9, the gamma function can be written as Γ(z)= Γ(z +1) z From the above expression it is easy to see that when z =0, the gamma function approaches ∞ or in other words Γ(0) is undefined. Given the recursive nature of the gamma function, it is readily apparent that the gamma function approaches a singularity at each negative integer. cshsrideshare.com https://summermthomes.com
