How do you convert #(0, - 3) # into polar coordinates? Precalculus Polar Coordinates Converting Coordinates from Polar to Rectangular 1 Answer sankarankalyanam Jul 9, 2018 #color(maroon)((r, theta) = (3, (3pi)/2)# Explanation: #(x,y) = (0, -3)# #r = sqrt(x^2 + y^2) = sqrt(0^2 + -3^2) = 3# #theta = arctan (y/x) = arctan (-3/0) = arctan(-oo) = -90^@ " or " (3pi)/2# Answer link Related questions What is the formula for converting polar coordinates to rectangular coordinates?
