How to solve for theta in sin 2 theta
WebGiven that d θ d x = − 12 sin 2 θ and d θ d y = 12 cos 2 θ, find: (a) the slope of the tangent line to the curve when θ = 12 π . d x d y 0 = π /12 = (b) the point(s) on the curve where the tangent line is horizontal. (Enter your answers as a … WebSolve the equation tan θ = 2 sin θ. What I did was rewrite it to the form sin θ = 2 sin θ cos θ You'll get sin θ = sin 2 θ. How am I supposed to solve this when I have sin on both sides? My main problem with these types of 'solve' equations are that I don't know which forms I should rewrite them too.
