WebThe assumption of x = cos θ and y = sin θ is valid as long as it is a unit circle including the pythagorean trig identity of cos^2 θ + sin^2 θ = 1. In the above problem, it is not mentioned that we are dealing with unit circle. My question - Can the pythagorean trig identity be used for any circle ? • ( 6 votes) Jerry Nilsson 2 years ago WebQuestion: Find all solutions in the interval [0,2pi) tan\theta = 2 sin\theta tan\theta.
