Question

Find the principal Argument for

z= i/(-2-2i)

Answer 1

I haven't done math in a while, I know how to do the hard parts, but I can't remember if I can change i/(-2-2i) = (i/-2) - (i/2i). Sad, I know

Answer 2

we will even each other out, I don't know how to do Arugment stuff

but
i/(-2-2i) = (i/-2) - (i/2i) isn't alowed, you can only separte them like this if it was flipped upside down.

Answer 3

that's what i thought! Thanks for the help! basically I just need to break this up into a real and an imaginary part and I can't figure it out for the life of me.

Answer 4

If I invert the entire equation can I then change the stuff around and invert it again to get back?

Answer 5

....stinking algebra

Answer 6

lol

Answer 7

so the idea is to separate the complex from the real?

Answer 8

yep. I need a real part and an imaginary part. Basically I need to consolidate my i terms

Answer 9

here is the best I got..
