Gamma function infinite product
WebA popular method of proving the formula is to use the infinite product representation of the gamma function. See ProofWiki for example. However, I'm interested in down-to-earth proof; e.g. using the change of variables. As the formula being connected to the beta function, there could be one-line proof for it. Could anyone help me? real-analysis WebInfinite Product. Download Wolfram Notebook. A product involving an infinite number of terms. Such products can converge. In fact, for positive , the product converges to a nonzero number iff converges. Infinite products …
