calculus - Computing the integral of log(sinx)

How to compute the following integral?
log(sinx)dx






Motivation: Since log(sinx)=cotx, the antiderivative log(sinx)dx has the nice property F(x)=cotx. Can we find F explicitly? Failing that, can we find the definite integral over one of intervals where log(sinx) is defined?
