    Graduate Solving Complex Identity: Help with z in Polar and Exponential Form

    I solved this a little earlier and got the same thing. Thanks for the help!

    Graduate Solving Complex Identity: Help with z in Polar and Exponential Form

    Oh, ok. I ended up getting 2z as well. But what doesn't make sense to me is that the original value should have no i (imaginary number) in it since we're taking the modulus. But after simplifying it, we get 2zm which would still have i in it.

    I got 4z^2-4 not 4z^2-1

    Graduate Solving Complex Identity: Help with z in Polar and Exponential Form

    Hi there. I need help simplifying the following: |\sqrt{z^2 -1} +z| + |\sqrt{z^2 -1} -z| What I did was I rewrote z in polar coordinates, but I ran into some difficulties taking the square root of r^2(cos2θ-sin2θ)-1. I also tried rewritting z in exponential form, but also had problems. Help?
