Complex Analysis mcqs with answers
Q.01
What is the residue of the function at the pole z = i?
a) 0
b) -1
c) 1
d) i
The residue of a function f(z) at a simple pole z = a is given by Res}(f, a) = \lim_{z \to a}(z – a)f(z)\)$. In this case, the residue at $\(z = i\)$ is $\(\lim_{z \to i}(z – i)\frac{1}{z^2 + 1} = -i\frac{1}{2i} = -1\)$.
b) -1
A. Abelian group w.r.t +
B. Ring
C. Field
D. All of the above
2. If z = 3-4i then conjugate of z lies in
Yes! Finally something about website.
