How do you convert (3, 2pi/3) into rectangular forms? Precalculus Polar Coordinates Converting Coordinates from Polar to Rectangular 1 Answer Alan P. Dec 1, 2015 polar form: (3,(2pi)/3) rarr rectangular form: (-3/2,(3sqrt(3))/2) Explanation: Given (r,theta) = (3,(2pi)/3) x= r*cos(theta) = 3*cos((2pi)/3) = 3*(-1/2) = -3/2 y = r*sin(theta)=3*sin((2pi)/3) = 3*(sqrt(3)/2) = (3sqrt(3))/2 Answer link Related questions What is the formula for converting polar coordinates to rectangular coordinates?
