Find the real part of `(1-i)^(-i)dot`

Explanation

To find the real part of \((1 - i)^{-i}\), we will follow these steps:

### Step 1: Convert \(1 - i\) to polar form
First, we need to find the modulus and argument of the complex number \(1 - i\).

- The modulus \(r\) is given by:
\[
r = |1 - i| = \sqrt{1^2 + (-1)^2} = \sqrt{1 + 1} = \sqrt{2}
