The online conjugate calculator returns the conjugate of a complex number.

Writing z = a + ib where a and b are real is called algebraic form of a complex number z :

- a is the real part of z;
- b is the imaginary part of z.

When b=0, z is real, when a=0, we say that z is pure imaginary.

The **conjugate of a complex number** `a+i⋅b`, where a and b are reals, is the complex number `a−i⋅b`.

For **calculating conjugate** of the **complex number** following z=3+i,
enter complex_conjugate(`3+i`) or directly 3+i, if the
complex_conjugate button already appears, the result 3-i is returned.

The complex numbers calculator can also determine the conjugate of a complex expression.
To **calculate the conjugate** of the following complex expression z=`(1+i)/(1-i)`,
enter complex_conjugate(`(1+i)/(1-i)`) or directly
(1+i)/(1-i), if the button complex_conjugate already appears, the result -i is returned.

With this function, the calculator allows the **online calculation of the conjugate** of a **complex number**.

complex_conjugate(z), z is a complex number.

complex_conjugate(`1+i`), returns 1-i
