I spend some time studying special functions recently. I found two definitions of gamma function, one in form of integral and the other in form of infinite products, and I cannot prove of their equivalence. I found the definition in infinite product form important in proofing many properties of gamma function such as gamma reflection formula, therefore I eager to learn it. Could anyone help me, please !(adsbygoogle = window.adsbygoogle || []).push({});
