In Complex Numbers, ‘conjugate’ is a term that’s widely used. Since it is already explained in Note 1, not many will be discussed.
The conjugate of is written as . With a bar on the top (I call it overline).
For instance, if , .
In the Argand plane, conjugate of a complex number corresponds to the reflection of the point in the real axis.
A conjugate of a complex number is just the imaginary part, with reversed signs.
For instance, the conjugate of the complex number would be .
