Homework Statement
Calculate the phasor notation for -43.62+j20.52
My answer is 180 degrees off and I don't know why you add it in this case. I just want to know how to calculate angle, the magnitude I found fine.
Homework Equations
tan-1(X/R)
The Attempt at a Solution
tan-1(20.52/-43.62) = -25.19 degrees
That's the answer I get but the answer is 180 degrees plus my result above resulting in 154.8 degrees
edit: I'm guessing it may be because it's in quadrant 2 or 3?
