Question #26517 Precalculus Polar Coordinates Converting Coordinates from Rectangular to Polar 1 Answer sjc Apr 17, 2017 #r^2=1# Explanation: we use the conversion equations #r^2=x^2+y"# #x=rcostheta# #y=rsintheta# so #x^2+y^2=1# becomes #r^2=1# Answer link Related questions What are the polar coordinates of #(0, -2)#?
