The article considers six types of integrals related with the powers of trigonometric functions. We can obtain the infinite series expressions of these integrals by using Taylor series expansions and integration term by term theorem. Moreover, we propose some integrals to do calculation and evaluate ...

A special basis based on trigonometric functions is proposed for solution of integral equations with kernels of the form K( x – t) by the Galerkin method. This basis possesses high approximation quality and allows one to reduce the double integral in the Galerkin algorithm to a very simple si...
Trigonometric Integrals: Trigonometric functions are continuous (at some intervals for some) and are differentiable. The derivative of any trigonometric function is either another single trigonometric function or a combination of them. Practically, trigonometric derivatives and integrals can be treated...
