Unit Vectors and Vectors in Two Dimensions

This topic is part of the HSC Mathematics Extension 1 syllabus under the topic Vectors.

In this post, we cover:

• How to convert a non-zero vector into a unit vector
• Define and use the direction of a vector in two dimension

Unit Vectors

Unit vectors are vectors that have a length of 1 (making them unitary) but can have any angle.
