trigonometric integral

Various expansions can be used for evaluation of Trigonometric integrals, depending on the range of the argument.

Certain trigonometric integrals have values expressible in terms of binomial coefficients:

In mathematics, the trigonometric integrals are a family of integrals which involve trigonometric functions.

A number of the basic trigonometric integrals are discussed at the list of integrals of trigonometric functions.

(possibly the earliest publication to use double factorial notation) states that the double factorial was originally introduced in order to simplify the expression of certain trigonometric integrals arising in the derivation of the Wallis product.
