Express in polar form: (-1-i)​

Given:

The complex number is

To find:

The polar form of given complex number.

Solution:

If z=a+ib, then

The polar form is .

Let the complex number is

Here, a=-1, b=-1. Both a and b are negative. So, z lies in III quadrant.

And,

    (because z lies in III quadrant)

Now, the polar form of given complex number is

Therefore, the required polar form is .
