Understanding non-component-wise operations

Not all vector operations are component-wise; some operations require more math. In this section, you are going to learn how to implement common vector operations that are not component-based. These operations are as follows:

• How to find the length of a vector
• What a normal vector is
• How to normalize a vector
• How to find the angle between two vectors
• How to project vectors and what rejection is
• How to reflect vectors
• What the cross product is and how to implement it

Let's take a look at each one in more detail.
