What is a complex number in short notes?
A complex number is any number of the form z = a + bi, where a and b are real numbers.
Note: All numbers involving i can be written in this form.
Notes: (.
- In z = a + bi, a is the real part of z
. b is the imaginary part of z.
What is the presentation of a complex number?
A complex number is a number that can be expressed in the form of a + ib where a represents the real part, and b is the imaginary part; i is the imaginary unit which is defined as the square root of -1, or we can have i as the solution of x2 = -1..
Why do we teach complex numbers?
Their use extends to different scientific branches, ranging from mathematics to engineering.
Complex numbers can also represent electromagnetic waves and electric currents, so they are essential in the field of electronics and telecommunications..

- Key Concepts
The horizontal axis is the real axis, and the vertical axis is the imaginary axis.
Complex numbers can be added and subtracted by combining the real parts and combining the imaginary parts.
Complex numbers can be multiplied and divided.
To multiply complex numbers, distribute just as with polynomials.
