Complex Conjugate
The complex conjugate of a + bi is a – bi, and similarly the complex conjugate of a – bi is a + bi. This consists of changing the sign of the imaginary part of a complex number. The real part is left unchanged.
Complex conjugates are indicated using a horizontal line over the number or variable. For example, .
Note: Complex conjugates are similar to, but not the same as, conjugates.
