The *Gamma function* satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral

You can render LaTeX mathematical expressions using KaTeX:

The Gamma function satisfying \Gamma(n) = (n-1)!\quad\forall n\in\mathbb NΓ(n)=(n1)!nN is via the Euler integral

\Pi(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.Π(z)=0tz1etdt.

MathJax basic tutorial and quick referenceAsk Question

  1. To see how any formula was written in any question or answer, including this one, right-click on the expression and choose "Show Math As > TeX Commands". (When you do this, the '$' will not display. Make sure you add these: see the next point. There are also other ways to view the code for the formula or the whole post.)

  2. For inline formulas, enclose the formula in $…$. For displayed formulas, use $$…$$.
    These render differently. For example, type
    $\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$
    to show ni=0i2=(n2+n)(2n+1)6 (which is inline mode) or type
    $$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$$
    to showni=0i2=(n2+n)(2n+1)6(which is display mode).
