Webb3 sep. 2014 · Here is a systematic procedure: Put e i x =: z and use Euler's formula to rewrite the given expression in terms of z. E.g., cos ( 4 x) = ( z 4 + z − 4) / 2. When an essential simplification is possible this will be reflected in the resulting rational function of z. In the case at hand the result is 1 + z 14 2 z 7 .
