How do you graph r=2costheta? - Socratic
Nov 12, 2016 · How do you graph r = 2 cos θ? The relation between polar coordinates (r,θ) and Cartesian coordinates (x,y) is given by. x = rcosθ, y = rsinθ and r2 = x2 +y2. Hence, r = 2cosθ ⇔ r2 = 2rcosθ or x2 + y2 = 2x. i.e. (x2 −2x + 1 + (y − 0)2 = 1. or (x − 1)2 +(y − 0)2 = 1.
