Chapter 2: Q28P (page 53)

Find the absolute value of each of the following using the discussion above. Try to do simple problems like these in your head-it saves time.
$\frac{z}{\bar{z}}$ .

Short Answer

Expert verified

The absolute value is 1.

Step by step solution

Given Information

The complex number is $\frac{z}{\bar{z}}$ .

Absolute value of the Complex number

Let z be a complex number consisting of two real numbers as:

$z = x + {}_{z}y$

Here x and y are the real numbers.

The absolute value of z can be calculated as:

$| z | = \sqrt{x^{2} = y^{2}}$

Find the value

The complex number is $\frac{z}{\bar{z}}$ .

The absolute value can be calculated as below:

$|z| = |\frac{x + y i}{x - y i}| = |\frac{x + y i}{x - y i}| = \frac{\sqrt{x^{2} + y^{2}}}{\sqrt{x^{2} = y^{2}}} |z| = 1$

Thus, the final answer is obtained as:

$|z| = 1$
