Homework Statement
Say how coordinate lines of the z plane transform when applied the following transformation
##e^z=\frac{a-w}{a+w}##
Homework Equations
The Attempt at a Solution
This is exactly the way the problem is stated. It is a pretty weird transformation in my opinion and I'm guessing ##w## is the transformation and the coordinate lines in question are cartesian coordinate lines.
That said I've solved for ##w##
##w=\frac{a(1-e^z)}{1+e^z}##
And what I've attempted to do is consider the cases ##x=C## ##y=C## where ##C## is some arbitrary constant and find an expression of the form ##w=u+iv##. This has proven quite tedious and very little if at all illuminating.
So I was wondering how I could proceed?
At first I thought this was similar to a bilinear transformation but now I've thought not at all.
I don't know this topic too well so I'm probably not seeing something basic here, or failing to identify the class of transformation in questionThanks.
