How do you find the rectangular coordinate of #(2, pi/5) #? Precalculus Polar Coordinates Converting Coordinates from Polar to Rectangular 1 Answer sankarankalyanam Jul 9, 2018 #color(purple)(x ~~ 1.618, y ~~ 1.176# Explanation: #(r, theta) = (2, (pi/5))# #x = r cos theta = 2 * cos (pi/5) ~~ 1.618# #y = r sin theta = 2 * sin (pi/5) ~~ 1.176# Answer link Related questions What is the formula for converting polar coordinates to rectangular coordinates?
