# Hyperbolic Functions resources

### Quick Reference (2)

The hyperbolic functions

This leaflet gives definitions of the hyperbolic functions in terms of exponential functions.
Graphs of the hyperbolic sine, cosine and tangent are illustrated. (Engineering Maths First Aid Kit 3.5)

The hyperbolic identities

This leaflet lists common identities involving the hyperbolic functions. (Engineering Maths First Aid Kit 3.6)

### Teach Yourself (1)

Hyperbolic functions

The hyperbolic functions have similar names to the trigonmetric functions,
but they are defined in terms of the exponential function. In this unit we
define the three main hyperbolic functions, and sketch their graphs. We also
discuss some identities relating these functions, and mention their inverse
functions and reciprocal functions.
