# Math Help - Converting binomial, polar, trigonometric, and rectangular equations

1. ## Converting binomial, polar, trigonometric, and rectangular equations

Ok guys heres the deal. The two specific equations i have to do are -6+2i and 4-5i. I need to convert them into the other three forms. I have ideas of what the two other forms but I'm stuck at making that trigonometric. Any help>?

Hint: there are three polar forms...

$z = x + iy = r(\cos{\theta} + i\sin{\theta}) = r\,\textrm{cis}\,{\theta} = re^{i\theta}$.
