Trigonometric integrals are a family of integrals which involve trigonometric functions. This family includes two pairs of functions: two simple trigonometric and two hyperbolic trigonometric integrals.

Sine and cosine integrals are defined as

Hyperbolic sine and cosine integrals are defined as

SineCosineIntegrals and HyperbolicSineCosineIntegrals subroutines are used to calculate trigonometric integrals.
