What is the rectangular coordinate form of the polar coordinates (r, pi/6)(r,π6) ? Precalculus Polar Coordinates Converting Equations from Polar to Rectangular 1 Answer George C. May 3, 2016 (r, pi/6)(r,π6) in polar form is (sqrt(3)/2 r, r/2)(√32r,r2) in rectangular form Explanation: theta = pi/6θ=π6 only gives you the angle. You need a radius too, but (r, pi/6)(r,π6) in polar form is (sqrt(3)/2r, r/2)(√32r,r2) in rectangular form. pi/6π6 is one half of an internal angle of an equilateral triangle.
