How do you convert the polar coordinate point #(3,135^o)# into rectangular form? Trigonometry The Polar System Polar Coordinates 1 Answer Douglas K. Jan 25, 2017 Use #x = (r)cos(theta) and y = (r)sin(theta)# Explanation: #x = 3cos(135^@)# #x = (-3sqrt(2))/2# #y = 3cos(135^@)# #y = (3sqrt(2))/2# The rectangular form is #((-3sqrt(2))/2,(3sqrt(2))/2)# Answer link Related questions What are Polar Coordinates?
