3. Assume that a, b, c, d e R such that ad - bc = 1. The transformation T :C\{-d/c} → C
defined by
az + b
T(z) :=
P + 25
is called Mobius transformation.
(a) Show that the transformation S: C\{a/c} C defined by
9 - zp
-cz + a
= (2)S
is the inverse of T, i.e., we have
S(T(z)) = T(S(z))
= z, for any z {a/c,-d/c}.
(b) Find a Mobius transformation T which satisfies:
T(0) = 1,T(1) = 2, T (2) = 5.
(c) What is the image of the unit circle D = {|z| < 1|z € C} under the Mobius transforma-
tion T(z) = -! (i.e., T(z) = )? Please show on your sketch what are the images of
the segments {0 <x< 1}, {iy|0 < y< 1} and {re'n/4 |r < 1}.
