Mehsin Jabel Atteya, Dalal Ibraheem Rasen · 2014
Abstract: The main purpose of this paper is to use the idea of finding the unlimited integration of the product of powers of the (sinz) and (cosz)-functions, and the product of powers of the (tanz) and (secz)-functions to derive tow trigonometrically identities.
