What is the distance between polar coordinates #(2, 120^circ)# and #(1, 150^circ)#? Precalculus Polar Coordinates Finding Distance Between Polar Coordinates 1 Answer sankarankalyanam Jul 9, 2018 #color(brown)("Distance " d = 1.2393# Explanation: #d = sqrt (r_1^2 + r_2 ^2 - 2 r_1 r_2 cos (theta_1 - theta_2))# #(r_1, theta_1) = (2, 120^@), (r_2, theta_2) = (1, 150^@)# #d = sqrt(2^2 + 1^2 - 2 * 2 * 1 * cos (120-150)# #d = sqrt (5 - 4 cos (-30)) ~~ 1.2393# Answer link Related questions What is the formula for the distance between two polar coordinates?
