The Gamma function is called “gamma” on the ClassPad.

(x)=  + tx–1etdt

For an integer n the gamma is evaluated as shown below.

{ (n – 1) !, n > 0 (n) = undefined, n 0

The gamma is defined for all real numbers excluding negative integers. It is also defined for all complex numbers where either the real or imaginary part of the complex number is not an integer.

Gamma of a symbolic expression returns unevaluated.
