Practice problem
Rewrite the product as a sum. 10cos(5x)sin(10x)\\10\cos(5x)\sin(10x)10cos(5x)sin(10x)
5sin(15x)+5sin(5x)5\sin(15x)+5\sin(5x)5sin(15x)+5sin(5x)
5cos(5x)−5cos(15x)5\cos(5x)-5\cos(15x)5cos(5x)−5cos(15x)
5cos(15x)+5cos(5x)5\cos(15x)+5\cos(5x)5cos(15x)+5cos(5x)
Type a concept, like “slope” or “photosynthesis”.
