SQA National 5 Maths Basics of vectors

Basics of vectors

This page covers the following topics:

1. Vector basics

Vector is a quantity with both a magnitude and a direction. In textbooks, vectors are denoted by a BOLD letter such as v. As it is hard to write bold letters in pen or paper, written work often uses different notation such as v, v, arrow or AB(arrow). The order of letters and arrows in the last example is important - in this case it tells us that the vector is going from point A to point B.
