# Thread: Complex numbers problem need help

1. ## Complex numbers problem need help

I hope you don't get mad but this is another long problem i have.

I really want to know how to do this i know what you mean but i don't how to start.

Given the Complex numbers Z1= -3+sqr.root of 3i and Z2= -1-i
respond to the following:

sketch a reasonable graph of Z2 (in the complex plane)

write Z2 in polar form

find the modulus of Z1

find (Z2)^7 (Hint: Try Big D's Theorem)

Z1 and Z2 i couldn't type it well but it suppose to be the 1 and 2 a little bit below the Z.

Really?! You can't find (-1,-1) on a Cartesian Coordinate system?

write Z2 in polar form
Square root of 2? 45º Reference Angle? What Quadrant?

find the modulus of Z1
Pythagorean Theorem

Please do your own homework. If you have been skipping class and failing to read your text, then you should be toast for the exam. A little review at this point will not help, particularly since it does not appear to be a review, but an initial introduction. You've never even heard the word "subscript?" I am not encouraged.

My views. I welcome others'.
