(Note that cos^2x=(cosx)^2, they are different ways of writing the same … WebDec 9, 2016 · 1 Link Answered: Karan Gill on 9 Dec 2016 I have a long equation with cosine with powers (e.g., (cos (a))^3, (cos (a))^5, ..). Then I need to reduce each power of cosine to unity (but angle is higher): e.g., (cos (a))^2 -> (1+cos (2a))/2. Here are more examples which reduce various powers: http://www.proofwiki.org/wiki/Power_Reduction_Formulas

Websin2x = 1 2 − 1 2cos(2x) = 1 − cos(2x) 2 and cos2x = 1 2 + 1 2cos(2x) = 1 + cos(2x) 2 are invaluable. These identities are sometimes known as power-reducing identities and they may be derived from the double-angle identity cos(2x) = cos2x − sin2x and the Pythagorean identity cos2x + sin2x = 1. Example 3.10 Integrating an Even Power of sinx Webcos x = ( u + v) / 2 Hence cos 4 x = 1 / 16 ( u + v) 4 = 1 / 16 ( u 4 + 4 u 3 v + 6 u 2 v 2 + 4 u v 3 + v 4) = 1 / 16 ( u 4 + u 2 + 6 + v 2 + v 4) Using Euler's identity again we have 2 cos 4 x = ( u 4 + v 4) 2 cos 2 x = ( u 2 + v 2) So cos 4 x = 1 / 16 ( 2 cos 4 x + 8 cos 2 x + 6) If you have sin term then you need scars martial arts system
