Complex conjugate
In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but with opposite sign. That is, if a {\displaystyle a} and b {\displaystyle b} are real numbers, then the complex conjugate of a + b i {\displaystyle a+bi} is a − b i {\displaystyle a-bi} . The complex conjugate of z {\displaystyle z} is often denoted as z ¯ {\displaystyle {\overline {z}}} or z ∗ {\displaystyle z^{*}} . In polar form, if r {\displaystyle...
