List of integrals of hyperbolic functions

List of integrals of hyperbolic functions

The following is a list of integrals (antiderivative functions) of hyperbolic functions. For a complete list of Integral functions, see list of integrals.

In all formulas the constant "a" is assumed to be nonzero, and "C"denotes the constant of integration.
