Example

Created on 2024-06-20Asked by Michael Mitchell (Solvelet student)

Determine if the function

f(z) = \frac{z}{z^2 + 1}

is analytic in the complex plane.

Solution

Step 1: Identify the function. The function is

f(z) = \frac{z}{z^2 + 1}.

Step 2: Determine where the function is undefined. The function is undefined where the denominator is zero:

z^2 + 1 = 0 \implies z = \pm i.

Step 3: Analyze the regions of analyticity. The function

f(z)

is analytic everywhere in the complex plane except at the points

z = i

and

z = -i

. Step 4: Conclusion. The function

f(z) = \frac{z}{z^2 + 1}

is analytic in the complex plane except at

z = \pm i

2. Determine whether the function

f(x) = \sqrt{x^2 + 1}

is analytic or not.,

DefinitionBasically, an analytic function means that at any point of its domain this function can have a local representation, meaning a converging power series around this point. These functions are smooth infinitely differentiable functions with high smoothness. This is true even for a function as 'simple' as the exponential function – ex is clearly analytic as it can be represented by the power series ∑n=0∞n! xn para todo x) que converge para los valores.
