- Somebody asked me this problem, but I think I left my complex numbers
- behind (or 'gave them back to my high school teachers' as my HS
- teachers said) so can anyone give me some pointer on it?
-
- The problem follows:
-
- Let f(z) = (az + b)/(cz + d) with ad - bc =/= 0 and a, b, c, d, z all
- complex. Suppose L is a straight line drawn in the complex plane,
- describe what f(L) could be.
