# Complex Numbers Exercise

## Given the complex numbers \( v = -3\sqrt{3} - 3i \) and \( w = 3i \), answer the following:

### (1.1) Plot the Complex Numbers (6 points)

- **Task:** Plot the complex numbers on the complex plane. Label them with \( v \) and \( w \).
- **Hint:** \( 3\sqrt{3} \approx 5.2 \).

#### Diagram Description:

The complex plane has a grid with real numbers along the horizontal axis (\( Re \)) and imaginary numbers along the vertical axis (\( Im \)). The numbers range from -6 to 6 on both axes.

### (1.2) Identify Real and Imaginary Parts (12 points)

- **Task:** Without the use of a calculator, identify the real and imaginary parts, and compute the modulus and the principal argument of \( v \) and \( w \).

| Complex Number | Real Part (\( Re \)) | Imaginary Part (\( Im \)) | Modulus (\( |z| \)) | Principal Argument (\( Arg \)) |
|----------------|-----------------------|---------------------------|--------------------|-------------------------------|
| \( v \)        |                       |                           |                    |                               |
| \( w \)        |                       |                           |                    |                               |

### (1.3) Rewrite in Polar Form (8 points)

- **Task:** Rewrite \( v \) and \( w \) in polar form, where \( r > 0 \) and \( 0 \leq \theta < 2\pi \).

### (1.4) Compute Product and Quotient (12 points)

- **Task:** Use the polar forms of \( v \) and \( w \) to calculate the product \( vw \) and the quotient \( \frac{v}{w} \). Write your answers in polar form.
