[Guan Zhaoqing]

Question:
              Find the limit of function at the given point, or explain why it does not exist.
              f(z)=|1-z|^2   at z0 = i.

Answer:
             lim z->i f(z) = |1-i|^2 = 1+1 =2

[Jiayue Wu]

$\lim \limits_{z_{0} \to i}\ f(x) = \lim \limits_{z_{0} \to i}\ |1-z|^2 = |1-i|^2 = 1^2+-(1)^2 = 2$
