Complex Conjugate

Definition : Let $a+bi$ be a complex number, its complex conjugate is $a-bi$.

The conjugate of a complex number is created simply by multiplying the imaginary term by$-1$. The conjugate can be used to find the magnitude of its complex number by multiplying them together. For example, the conjugate of $5-3i$ is $5+3i$. By multiplying $(5-3i)(5+3i) = 25+9=34$ which is the magnitude of $5+3i$. If $z$ is a complex number its conjugate is represented as $\bar{z}$.
