2. Angle A; side b
3. Angle B;Angle A

TanA × Tan2A = 1

Prove sin3A + cos3A = 1

Find at least one solution to the following equation:

sin(x^2 − 1)/1 − sin(x^2 − 1) = sin(x) + sin^2(x) + sin^3(x) + sin^4(x) + · · ·

Find at least one solution to the following equation:
(sin(x^2 − 1))/(1 − sin(x^2 − 1)) = sin(x) + sin^2(x) + sin^3(x) + sin^4(x) + · · ·
