The integrals in Gradshteyn and Ryzhik. Part 5: Some trigonometric integrals

摘要

We present evalauations and provide proofs of definite integrals involvingthe function x^p cos^n x. These formulae are generalizations of 3.761.11 and3.822.1, among others, in the classical table of integrals by I. S. Gradshteynand I. M. Ryzhik.
