I have to turn this homework in online... I just want someone to check my work
Convert from Cartesian coordinates to Polar coordinates
if r > 0 and if r < 0.
The Attempt at a Solution
if r > 0 then I believe the answer is
(r,∅) = (2,4.2)
if r < 0 then i'm a bit confused, is the only difference I make the 2 negative?
(r,∅) = (-2,4.2)
