### Function : imaginary_part

#### Summary :

The imaginary_part function calculates online the imaginary part of a complex number.

Imaginary_part online

#### Description :

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.

For calculating conjugate of the complex number following z=1+7i, enter imaginary_part(1+7i) or directly 1+7i, if the imaginary_part button already appears, the result 7 is returned.

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

With this function, the calculator allows the online calculation of the imaginary part of a complex number.

The imaginary_part function calculates online the imaginary part of a complex number.

#### Syntax :

imaginary_part(z), z is a complex number.

#### Examples :

imaginary_part(1+7i), returns 7
