The density of the Beta distribution is defined by

$P(x) = \frac{(1-x)^{\beta-1} x^{\alpha-1}}{B(\alpha, \beta)}$

$P(x) = \frac{\Gamma(\alpha + \beta)}{\Gamma(\alpha) \Gamma(\beta)} (1-x)^{\beta-1} x^{\alpha-1}$

x	the value at which to evaluate the function, must be in range 0..1
a	the 1st number of degrees of freedom, must be strictly positive
