29.7.6.4 Beta function [sf.cmath.beta]
floating-point-type beta(floating-point-type x, floating-point-type y); float betaf(float x, float y); long double betal(long double x, long double y);
Effects: These functions compute the beta function of their respective argumentsx and y.
Returns: B(x,y), where B is given by Formula 29.24,x is x andy is y.
B(x,y)=Î(x)Î(y)Î(x+y) , for x>0, y>0(29.24)
