Find the modulus and the arguments of the complex number `z = - 1 - isqrt(3)`

Explanation

To find the modulus and argument of the complex number \( z = -1 - i\sqrt{3} \), we will follow these steps:

### Step 1: Identify the real and imaginary parts
The complex number \( z \) can be expressed in the form \( z = a + bi \), where:
- \( a = -1 \) (the real part)
- \( b = -\sqrt{3} \) (the imaginary part)

### Step 2: Calculate the modulus
