1. The problem statement, all variables and given/known data find linear fractional transformation that carries circle |z|=1 onto the line Re((1+i)w)=0 2. Relevant equations linear fractional transformation is of the form az+b/cz+b where ad-bc≠0 3. The attempt at a solution Re((1+i)w)=0 means that the line is just the y axis, but then I am unsure.. I think I might have to pick points and figure out the transformation that maps the points where i want them to go?
