### Quick Reference (1)

Graphs of the trigonometric functions

This leaflet gives graphs of the functions
sine, cosine and tangent and notes some important properties. (Engineering Maths First Aid Kit 4.3)

### Teach Yourself (1)

Trigonometric functions

The sine, cosine and tangent of an angle are all defined in terms of
trigonometry, but they can also be expressed as functions. In this unit we
examine these functions and their graphs. We also see how to restrict the
domain of each function in order to define an inverse function.
