Write the complex number in polar form.

### Converting Complex Numbers to Polar Form

This exercise helps in understanding the conversion of complex numbers to their polar form and representing them in the complex plane.

#### Task Description
1. **Given Problem:**
   - **Objective:** Plot the complex number in the complex plane and write it in polar form.
   - **Complex Number:** \(4 + 4i\)

2. **Steps to Follow:**
   - **Plot the complex number:** Position the complex number on the complex plane appropriately.
   
3. **Complex Plane Visualization:**
   - **Imaginary axis (vertical) and Real axis (horizontal).** Three graphs are shown:
     1. **Graph A:**
        - \(+10\) to \(-10\) on both axes with the point plotted on coordinates (4, 4).
     2. **Graph B:**
        - Similar to Graph A with the point marked correctly and highlighted with a green checkmark.
     3. **Graph C:**
        - The point is plotted incorrectly on \((4, -4)\).

#### Polar Form Conversion

   - **Formula:** 
     \[ z = r (\cos(\theta) + i \sin(\theta)) \]
   - **Instructions for solution:**
     - **Enter the correct modulus \(r\) and argument \(\theta\).** (Answer box provided)
     - **Type the exact answer in the first box** for \(r\).
     - **Type the angle in degrees** in the second box for \(\theta\). Make sure the angle measure is between \(0^\circ\) and \(360^\circ\).
     
#### Input Fields:
   - **Modulus (r):** Type an exact answer.
   - **Argument (\theta):** Type any angle in degrees.

#### Actions:
   - **Check Answer:** Available at the bottom to verify the solution.
   - **Clear All:** To reset input fields.

Use this guide to carefully plot the given complex number \(4 + 4i\), convert it to polar form, and input your calculated values.
