Convert the complex number `z=(i-1)/(cospi/3+isinpi/3)`in the polar form.

Explanation

To convert the complex number \( z = \frac{i - 1}{\cos \frac{\pi}{3} + i \sin \frac{\pi}{3}} \) into polar form, we will follow these steps:

### Step 1: Simplify the denominator
First, we need to evaluate \( \cos \frac{\pi}{3} \) and \( \sin \frac{\pi}{3} \):
\[ \cos \frac{\pi}{3} = \frac{1}{2}, \quad \sin \frac{\pi}{3} = \frac{\sqrt{3}}{2} \]
Thus, we can rewrite the denominator:
