Introduction

In mathematics, complex numbers are numbers that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, which satisfies the equation i^2 = -1. Complex numbers are used to represent points in a two-dimensional plane, and they have numerous applications in various fields, including algebra, geometry, and calculus. One of the fundamental concepts in complex numbers is the midpoint, which is the point that divides a line segment into two equal parts. In this article, we will discuss how to find the midpoint of two complex numbers.

What is a Midpoint?

A midpoint is a point that divides a line segment into two equal parts. In the context of complex numbers, the midpoint of two complex numbers z1 and z2 is the complex number that lies exactly in the middle of the line segment joining z1 and z2. The midpoint is denoted by the symbol (z1 + z2)/2.

Finding the Midpoint of Two Complex Numbers

To find the midpoint of two complex numbers z1 and z2, we can use the following formula:

Midpoint = (z1 + z2)/2

where z1 and z2 are complex numbers in the form a + bi.

Example: Finding the Midpoint of Two Complex Numbers

Let's consider two complex numbers z1 = 0 + 7i and z2 = 9 - 10i. We want to find the midpoint of these two complex numbers.

import cmath
z1 = complex(0, 7)
z2 = complex(9, -10)
midpoint = (z1 + z2) / 2

Step-by-Step Solution

To find the midpoint of two complex numbers z1 and z2, we can follow these steps:

Add the real parts of z1 and z2 to get the real part of the midpoint.
Add the imaginary parts of z1 and z2 to get the imaginary part of the midpoint.
Divide the real part of the sum by 2 to get the real part of the midpoint.
Divide the imaginary part of the sum by 2 to get the imaginary part of the midpoint.

Midpoint Formula

The midpoint formula for two complex numbers z1 and z2 is:

Midpoint = (z1 + z2)/2

where z1 and z2 are complex numbers in the form a + bi.

Properties of the Midpoint

The midpoint of two complex numbers has several important properties:

The midpoint lies exactly in the middle of the line segment joining the two complex numbers.
The midpoint is equidistant from the two complex numbers.
The midpoint is the average of the two complex numbers.
