대답:

# (sqrt (170), tan ^ -1 (1/13)) - = (13.0,0.0768 ^ c) #

설명:

주어진 좌표 집합 # (x, y) #, # (x, y) -> (rcostheta, rsintheta) #

# r = sqrt (x ^ 2 + y ^ 2) #

# theta = tan ^ -1 (y / x) #

# r = sqrt (13 ^ 2 + 1 ^ 2) = sqrt (169 + 1) = sqrt (170) = 13.0 #

# theta = tan ^ -1 (1/13) = 0.0768 ^ c #

# (13,1) -> (sqrt (170), tan ^ -1 (1/13)) - = (13.0,0.0768 ^ c) #
