how to find the table integral that contains factorial of n?

35 Views Asked by At

I read in this page that" There are lots of definite integrals that depend on a parameter n∈N and whose result contains factorials of n " I am really struggle with this integral \begin{align*} \int_{0}^{\infty} \frac{(t)^n}{(1+t)^{2j+2}}dt = \sum_{n=0}^{2j} [\frac{(2j- n)! n!}{(2j+1)!}] \end{align*}\ All what I want where can I find the table integral that contains factorial of n and satisfy the above relation? I hope at least, anybody can help me to find the table integral that contains factorial of n
