. what is conjugate of a complex number
A complex conjugate of a complex number is some other complex number whose actual part is similar to the unique complex number and the magnitude of the imaginary part is the same with the opposite sign. A complex number is of the form a + ib, where a, b are real numbers, a is known as the real part, b is known as the imaginary part, and that i is an imaginary number same to the root of negative 1. The complex conjugate of a + ib with actual part 'a' and imaginary part 'b' is given by a - ib whose real part is 'a' and imaginary part is '-b'. a - ib is the reflection of a + ib about the real axis (X-axis) in the argand plane. The complex conjugate of a complex number is used to rationalize the complex number.
