How to solve for theta angle
WebOct 4, 2015 · Unless c 1, c 2 are both zero (hence θ 2 = θ 1 − π ), solution to (5) provides us with sin θ 1 and cos θ 1 (check that sin 2 θ 1 + cos 2 θ 1 ≡ 1 ). Together with (1) and (2) we can get the sin and cos of the other angle. Also, hence the system is symmetric, the solution is either { θ 1, θ 2 } or . Share.
