WebAug 13, 2024 · This is a quadratic equation for r whose solutions are. r = 4 cos θ ± 16 cos 2 θ − 16 ( cos 2 θ − 1) 2 cos 2 θ − 2 = 4 ( cos θ ± 1) 2 ( cos 2 θ − 1). Since r is non-negative and the denominator is non-positive, we must take the solution. r = 4 ( cos θ − 1) 2 ( cos θ − 1) ( cos θ + 1) = 2 cos θ + 1. Share.

WebFeb 20, 2024 · Taking a complex number in rectangular form and converting it to polar form: finding the modulus and argument WebDec 1, 2014 · x = rcosθ. y = rsinθ. To convert from rectangular to polar: r2 = x2 +y2. tanθ = y x. This is where these equations come from: Basically, if you are given an (r,θ) -a polar coordinate- , you can plug your r and θ into your equation for x = rcosθ and y = rsinθ to get your (x,y).
