Practice problem
Rewrite in terms of sin(x)\sin(x)sin(x) and cos(x)\cos(x)cos(x). cos(x+2π3)\\\cos(x+\frac{2\pi}3)cos(x+32π)
−12cos(x)+32sin(x)-\frac12\cos(x)+\frac{\sqrt3}2\sin(x)−21cos(x)+23sin(x)
−12cos(x)−32sin(x)-\frac12\cos(x)-\frac{\sqrt3}2\sin(x)−21cos(x)−23sin(x)
−12sin(x)+32cos(x)-\frac12\sin(x)+\frac{\sqrt3}2\cos(x)−21sin(x)+23cos(x)
−12sin(x)−32cos(x)-\frac12\sin(x)-\frac{\sqrt3}2\cos(x)−21sin(x)−23cos(x)
Type a concept, like “slope” or “photosynthesis”.
