WebA complex number is a number of the form a + b i where. a. a is the real part of the complex number. b. b is the imaginary part of the complex number. If b = 0, then a + b i is a real number. If a = 0 and b is not equal to 0, the complex number is called a pure imaginary number. An imaginary number is an even root of a negative number. WebMay 22, 2024 · Definition of Complex number. A complex number, z, consists of the ordered pair (a,b ), a is the real component and b is the imaginary component (the i is suppressed because the imaginary component of the pair is always in the second position). The imaginary number ib equals (0,b ). Note that a and b are real-valued numbers. …

WebSep 16, 2024 · We define the number i as the imaginary number such that i2 = − 1, and define complex numbers as those of the form z = a + bi where a and b are real numbers. We call this the standard form, or Cartesian form, of the complex number z. Then, we refer to a as the real part of z, and b as the imaginary part of z. WebComplex numbers enable us to solve equations that we wouldn't be able to otherwise solve. Examine the following example: x 2 = − 11 x = − 11 11 ⋅ − 1 = 11 ⋅ i i 11 Without the ability to take the square root of a negative number we would not be able to solve these kinds of problems.
