1. The problem statement, all variables and given/known data I need to find the complex angle θ for: 2√(3)-2i in polar form. 2. Relevant equations 3. The attempt at a solution If I draw a complex plane, I can see that 2√3 on the real axis gives 0°, and -2i gives 3π/2 (270°), but it's incorrect. How can I find the complex angle of 2√(3)-2i? Thanks in advance.
