# Trigonometry

Chapter

## Abstract

When we split the word ‘trigonometry’ into its constituent parts, ‘*tri*’ ‘*gon*’ ‘*metry*’, we see that it is to do with the measurement of three-sided polygons, i.e., triangles. It is a very ancient subject, and one the reader requires to understand for the analysis and solution of problems in computer graphics.

Trigonometric functions arise in vectors, transforms, geometry, quaternions and interpolation, and in this chapter we survey some of the basic features with which the reader should be familiar.
