Practice problem
Rewrite in terms of sin(x)\sin(x)sin(x) and cos(x)\cos(x)cos(x). cos(x−5π4)\\\cos(x-\frac{5\pi}4)cos(x−45π)
−22cos(x)−22sin(x)-\frac{\sqrt2}2\cos(x)-\frac{\sqrt2}2\sin(x)−22cos(x)−22sin(x)
−22cos(x)+22sin(x)-\frac{\sqrt2}2\cos(x)+\frac{\sqrt2}2\sin(x)−22cos(x)+22sin(x)
−22sin(x)−22cos(x)-\frac{\sqrt2}2\sin(x)-\frac{\sqrt2}2\cos(x)−22sin(x)−22cos(x)
Type a concept, like “slope” or “photosynthesis”.
