opic 8 Notes 8 Residue Theorem

by J Orloff · Cited by 2 — f(z) = z + 1 z3(z2 + 1) has isolated singularities at z = 0,±i and a zero at z = −1. We will show that z =0isa pole of order 3, z = ±i are poles of order 1 and ...

Answer 2

Answer:

f (2) = 1

Step-by-step explanation:

given: z=2

f (z) = 1/(z-1)(z-2)

f (2) = 1/(2-1)(2-2)

f (2) = 1/1*1

f (2) = 1/1

f (2) = 1
