Practice problem
Verify csc(x)\csc(x)csc(x) - cot(x)\cot(x)cot(x) = 1csc(x)+cot(x)\frac{1}{csc(x) + cot(x)}csc(x)+cot(x)1.
csc2(x)\csc^2 (x)csc2(x) - cot2(x)\cot^2 (x)cot2(x) = 1
1 = sin2(x)\sin^2 (x)sin2(x) - cot(x)\cot (x)cot(x)
cos(x)−1\cos(x) - 1cos(x)−1 = sin2(x)\sin^2 (x)sin2(x)
Type a concept, like “slope” or “photosynthesis”.
