Web18 Aug 2014 · 2 Answers Sorted by: 11 trigsimp, as Aristocrates points out, does the reverse, because sin (x) + sin (y) is simpler than 2*sin ( (x + y)/2)*cos ( (x - y)/2). trigsimp internally uses an algorithm based on a paper by Fu, et. al., which does pattern matching on various trigonometric identities. Web7 Mar 2011 · Fullscreen. De Moivre's theorem, along with the binomial theorem, can be used to expand functions like or , where is an integer, into a sum of powers of trig functions consisting of a mixture of sines and cosines. In some cases it is possible to rewrite the expansion such that it contains all sines or all cosines by making use of the identity .
