Luo, Qiu-Ming and Guo, Bai-Ni (2000) Evaluation of the Improper Integrals ∫∞0(sin(βx)/x)^n dx. RGMIA research report collection, 4 (4).


In this article, using the trigonometric power formulae, the L’Hospital rule and integration by parts, some evaluations for the improper integrals ∫∞0(sin x/x)^n dx and ∫∞0(sin(βx)/x)^n dx for positive integer n ≥ 2 and β ≠ 0 are established. As by-products, three combinatorial identities are obtained.
