Arcsine distribution

In probability theory, the arcsine distribution is the probability distribution whose cumulative distribution function is

for 0  x  1, and whose probability density function is

on (0, 1). The standard arcsine distribution is a special case of the beta distribution with α = β = 1/2. That is, if X is the standard arcsine distribution then X \sim {\rm Beta}(\tfrac{1}{2},\tfrac{1}{2}) \
