WebSo we have two equations: rcos a = a (1) rsin a = -b (2) We can find a by dividing (2) by (1): sin a /cos a = -b/a , hence tan a = -b/a which we can solve. We can find r by squaring and adding (1) and (2): r 2 cos 2a + r 2 sin 2a = a 2 + b 2 hence r 2 … WebFeb 1, 2024 · Solution: Transform it to a product, using trig identities: cos 2x (2cos x + 1 ) = 0. Next, solve the 2 basic trig equations: cos 2x = 0, and (2cos x + 1) = 0. Example 8. Solve: sin x - sin 3x = cos 2x. (0 < x < 2Pi) Solution: Transform it into a product, using trig identities: -cos 2x* (2sin x + 1) = 0.
