how do i get sinh(z) = some u + iv form???? - Jan 7th 2009, 12:44 PMMush

Here you have a complex number which is composed of subtraction of two complex numbers.

Remember that if and are complex numbers then:

In this case

And you're trying to find

Get in a nicer form by multiplying top and bottom by the conjugate of the denominator first.

Hence

Should be relatively easy to find the conjugate now. - Jan 7th 2009, 01:00 PMcrb
