Complex Number Division Formula
Complex Number Division Formula
Complex Number Division Formula is a little more difficult than addition, subtraction, and multiplication of complex numbers because it is difficult to divide a number by an imaginary number. To better Complex Number Division Formula, students must find a term by which students can multiply the numerator and denominator and eliminate the imaginary part of the denominator, resulting in a real number in the denominator.
In this article, students will learn Complex Number Division Formula, divide complex numbers in polar form, divide imaginary numbers, and divide complex fractions.
Dividing Complex Numbers
To find the square root of a negative number, use the Complex Number. In the first century, Hero of Alexandria, a Greek mathematician, mentioned the Complex Number when attempting to find the square root of a negative number. He simply changed the negative to a positive and calculated the numeric root value. Furthermore, while searching for the negative roots of cubic and quadratic polynomial expressions in the 16th century, Italian mathematician Gerolamo Cardano defined the real identity of a Complex Number.
Complex Number is used in many scientific fields, including signal processing, electromagnetism, fluid dynamics, quantum mechanics, and vibration analysis. Students can learn about the Complex Number’s definition, terminology, visualization, properties, and operations here.
What is Dividing Complex Numbers?
Now that students have established what Complex Number Division Formula entails, let’s go over the steps involved. Follow the steps below to Complex Number Division Formula:
First, compute the conjugate of the complex number in the fraction’s denominator.
Multiply the conjugate by the complex fraction’s numerator and denominator.
In the denominator, use the algebraic identity (a+b)(a-b)=a2 – b2 and substitute i2 = -1.
Simplify by using the distributive property in the numerator.
Separate the resultant complex number’s real and imaginary parts.
Dividing Complex Numbers Formula
A complex number is the product of a real number and an imaginary number. These are the numbers that can be written in the form a+ib, where a and b are both real numbers. It is represented by the symbol z.
In complex number form, the value ‘a’ is known as the real part, which is denoted by Re(z), and ‘b’ is known as the imaginary part im. In the complex number form a +bi, ‘i’ is an imaginary number called “iota.”
Steps for Dividing Complex Numbers
To Complex Number Division Formula, follow these steps:
The procedure of splitting two complex numbers differs slightly from that of dividing two real numbers. It is the concept of rationalizing the denominator in fractions using irrational integers as denominators.
Step 1: Confirm that both the numerator and denominator are in the normal complex number form, i.e., z = a + ib.
Step 2: Determine the conjugate of the complex number in the fraction’s denominator. Assume the denominator is a + bi, and the conjugate is a bi.
Step 3: Multiply the numerator and denominator by the conjugate or both fraction terms.
Step 4: Using the distributive property, simplify the numerator.
Step 5: Using the difference of squares formula, simplify the denominator. Specifically, (a+b)(a-b) = a2 – b2
Step 6: Separate the real and imaginary elements of a complex number at the end.
This is how the Complex Number Division Formula is done.
Division of Complex Numbers in Polar Form
Students have a new sort of complex number representation known as the polar form of a complex number with the modulus and argument of a complex number, as well as its representation in the argand plane. In polar form, the complex number z = a + ib is represented by z = r (Cos + iSin).
