Closed-form evaluation of some families of cotangent and cosecant integrals
Several families of integrals involving the cotangent or cosecant function have been evaluated in closed form by making use of elementary arguments. Some of them are expressible in terms of the values of the (generalized) Clausen function and Hurwitz zeta function.
