回答:

#(SQRT(170),棕褐色^ -1(1/13)) - =(13.0,0.0768 ^ C)#

说明:

对于给定的坐标集 #(X,Y)#, #(X,Y) - >(rcostheta,rsintheta)#

#R = SQRT(X ^ 2 + Y ^ 2)#

#THETA =黄褐色^ -1(Y / X)#

#R = SQRT(13 ^ 2 + 1 ^ 2)= SQRT(169 + 1)= SQRT(170)= 13.0#

#THETA =黄褐色^ -1(1/13)= 0.0768 ^ C#

#(13,1) - >(SQRT(170),棕褐色^ -1(1/13)) - =(13.0,0.0768 ^ C)#
