WebbWe would rather wish to rewrite sin(14*x) and cos(14*x) in terms of sin(7*x) and cos(7*x). This is possible, but only with a trick: We have to replace 14*x with 2*y: simp1, 14*x=2*y; 9 sin(2 y) ----- 7 cos(2 y) + 7. Now we can apply trigexpand: trigexpand(%); 18 cos(y) sin(y) ----- 2 2 7 (cos (y) - sin (y)) + 7 trigsimp(%); 9 sin(y) ----- 7 cos(y)
