Represent the complex number `z=1+isqrt3` in 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 can be expressed as:
- Real part: \( a = 1 \)
- Imaginary part: \( b = \sqrt{3} \)

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