Question

The singular point of the function f(z) = e2/(z2+1)(z)
that lie inside |z-i| = 1/2 ar
are
(22+1)(2)
Select one:
O a. z=0 and z=i
O b. z=0 and z=-i
O c. z=i and z=-i
d. z=0 and z=1​

Answer 1

Answer:

a. z=0 and z=i

Step-by-step explanation:

therefore the function f(z) is not analytic at the point 0 and i
