Represent the complex number `z = 1 +isqrt(3)`in the polar form.

Explanation

To represent the complex number \( z = 1 + i\sqrt{3} \) in polar form, we will follow these steps:

### Step 1: Identify the real and imaginary parts
The complex number \( z \) can be expressed as:
- Real part (\( a \)): \( 1 \)
- Imaginary part (\( b \)): \( \sqrt{3} \)

### Step 2: Calculate the modulus \( r \)
