Change these rectangular coordinates to polar coordinates: (3, -3).
Give your answer in degrees and simplify all radicals., if necessary.
~~~~~~~~~~~~~~~~

The modulus is  r = sqrt%283%5E2+%2B+%28-3%29%5E2%29 = 3%2Asqrt%282%29.


The argument is  a = arctan%28%28-3%29%2F3%29 = arctan%28-1%29 = -45°.


The polar form is  (r,a) = (3sqrt%282%29,-45°).      ANSWER

Solved.
