mapping
any hint about this question and some basics
Q-Show that under the transformation function W=1/Z , the circle defined by |Z-3|=5 is mapped into a circle |W+3/16|=5/16 in the W-plane

Re: mapping
hi ammar,
I do these like this:
let W = x + iy so Z = 1/(x + iy)
You can re-arrange this to get the required equation for that circle.
