A good method to expand sin(7x) sin (7 x) is by using De Moivre's theorem (r(cos(x)+i ⋅sin(x))n = rn (cos(nx)+i⋅sin(nx))) (r (cos (x) + i ⋅ sin (x)) n = r n (cos (n x) + i ⋅ sin (n x))). When r = 1 r = 1, cos(nx)+i ⋅sin(nx) = (cos(x)+ i⋅sin(x))n cos (n x) + i ⋅ sin (n x) = (cos (x) + i ⋅ sin (x)) n.
