# Conjugate of x+iy is

The complex conjugate of x+iy is x-iy. Whereas the complex conjugate of x-iy is x+iy.

As we know every complex number is associated with another complex number called the complex conjugate.

Here, the real part of the complex conjugate is same as the original complex number, whereas the imaginary part is also same as the original complex number, but with the opposite sign.

For example, the complex conjugate of 2+3i is 2-3i.
