Chapter 1: Q2P (page 1)

First simplify each of the following numbers to the $x + i y$ form or to the $r e^{i 胃}$ form. Then plot the number in the complex plane.
$\frac{1}{1 - i}$ .
.

Short Answer

Expert verified

Rationalize the complex number.

$\begin{array}{rcl} \frac{1}{i - 1} & = & \frac{1}{i - 1} 路 \frac{i + 1}{i + 1} \\ = & \frac{i + 1}{i^{2} - i^{2}} \\ = & \frac{i + 1}{- 2} \\ = & - \frac{1}{2} - \frac{i}{2} \end{array}$

The complex number is $- \frac{1}{2} - \frac{i}{2}$ .

Step by step solution

Given Information

The complex number is $\frac{1}{1 - i}$ .

Definition of the Complex number

A complex number is a number that is made up of both real and imaginary numbers

Find the value

Rationalize the complex number.

$\begin{array}{rcl} \frac{1}{i - 1} & = & \frac{1}{i - 1} 路 \frac{i + 1}{i + 1} \\ = & \frac{i + 1}{i^{2} - i^{2}} \\ = & \frac{i + 1}{- 2} \\ = & - \frac{1}{2} - \frac{i}{2} \end{array}$

Hence, the complex number is $- \frac{1}{2} - \frac{i}{2}$ .

The graph is mentioned below.
