operation on complex numbers in which the sign of the real part is kept but the sign of the imaginary part is reversed
A complex conjugate is formed by flipping the sign of the imaginary part of a complex number while keeping the real part unchanged. This operation is useful in mathematics and engineering because multiplying a complex number by its conjugate eliminates the imaginary part, producing a real number.
