Question

Express the complex number in trigonometric form.

3 - 3i

Answer 1

Real and imaginary are the same magnitude. There's a 45º (\(\pi/4\)) reference angle in your future. You just have to decide which Quadrant.

Answer 2

quadrant 4 but would it be 7pi over 4 or 5pi over 4

Answer 3

Hopefully, you will see that 5pi/4 is in Quadrant III.

I'd prefer \(-\pi/4\) unless someone insists on it being positive.

Answer 4

Thank you very much !
