Please select a resource from the list below.

Quick Reference

• 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.
• The hyperbolic identities
  This leaflet lists common identities involving the hyperbolic functions.

Teach Yourself

• 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.

A transcript of each video should be available in the Teach Yourself section above.

These videos require Windows Media Player (v10).

Please note: You may experience trouble with more recent upgrades to Internet Explorer (now v.7) and Media Player (now v.11). These no longer support streaming from the mms servers used by mathcentre, so we are recommending that you uninstall IE7 (IE6 lies underneath) and replace the new version of WMP with the fully functioning v.10 (you may need to find a download via google after uninstalling v.11). All those that have done this have reported back that everything is working again.
