Moreover, if the terminals of integration are say a a and b b (not zero or infinity), the definite integral would be ln(a) − ln(b) l n ( a) − l n ( b). These identities are sometimes known as power-reducing identities and they may be derived from the double-angle identity cos (2 x) = cos 2 x − sin 2 x cos (2 x) = cos 2 x − sin 2 x and the Pythagorean identity cos 2 x + sin 2 x = 1. (Note that cos2x = (cosx)2, they are different ways of writing the same thing.
