There are actually more trigonometric functions in existence than most of us know about. The functions versine, coversine, exsecant and excosecant are no longer taught in schools; in some European countries, neither are secant, cosecant and cotangent. In this Demonstration, these archaic trigonometric functions are plotted, and their relationships with the basic trigonometric functions sine, cosine and tangent are exhibited.
