A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1)
The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas:
a + bi + c + di = (a+c) + (b+d)i (addition)
a + bi − (c + di) = (a−c) + (b−d)i (subtraction)
(a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication)
(a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division)
You can obtain the Absolute Value for a complex number using the following formula:
|a + bi| = √(a2 + b2)
A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.
