Hello all,

I was hoping for some help on turning complex number to polar form. I'm working on a nonhomogenous difference equation, and while solving I got the roots .

Ok, so far so good. The modulus, , which gives me . Then the argument, . This gives me . Is this correct?

The root I got, , when I want to find , what value of b do I use (because of the )? The negative or positive value of ?

Is there any way to make the argument a "pretty" -fraction (if it exists)?

Thank you for any help!
