The Attempt at a Solution


I forgot how, I had no clue so I looked in the solutions and it was 2.62 radians, I just dont know how they got that, im not sure on what to do. Its for trigonometric forms of complex numbers.


Thanks for any help!

You don't have a calculator or something?
Usually that's the way to solve a problem like this, unless you want to iterate it...
