Hello everyone

I've got a problem with these two questions:

Express the following complex numbers in real and imaginary parts :

z=6ln(1+j)

z=1/cos^2(1/2 j ln (j))

I'm completely stuck, any hints will be much appreciated.

Suppose that

$\displaystyle a+jb \equiv re^{j(\theta+2k\pi)},$

then

$\displaystyle \ln(a+jb) = \ln (r) + j(\theta + 2k\pi).$ - Dec 31st 2012, 04:19 AMaka74Re: Complex numbers - express in real and imaginary parts
Thanks a lot, I've got it sorted now.
