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 don't know how they got that, I am 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...
 
Whats do i type in? A friend told me to do the arctan of 2/5 but that just gives me some decimal.
 
Is your calculator in DEG? if not, then put it in RAD
