## Introduction

**Ray Tracing** is an algorithm used to create realistic graphics.

## Sub-problem No. 1

Any Ray Tracing algorithm requires the representation of objects in a 3D space.

A vector is a line segment that extends from point A to point B in a 2D or 3D plane.

We need to be able to operate on vectors.

Normalizing a vector involves scaling its magnitude/size to 1 while retaining its direction. This can be useful for other operations such as distance calculation or clustering.

The formula for the cross product is given by:

To implement the calculation, the following steps were taken:

- Create an empty list called `new_result`

- Iterate over the vector `result`

- In each iteration, add the previous value to the next one

- Store this result in `new_result`

- Display `new_result`

To calculate the magnitude of a vector:

### Steps

- Iterate over the vector elements

- Square each element

- Sum the squared values

- Take the square root of the resulting value

### Resources

- `for` loop

- `math.Pow(2, 10)`

- `append`

### Plan

- Iterate over the vector `v1[x]`

- Square each `v1[x]`

- Store the squared values in another vector `[x]`

- Sum the values in this new vector `[x]`
