# Hyperbolic trigonometric functions

### From Conservapedia

The **hyperbolic trigonometric functions** are analogs of the standard trigonometric functions using a hyperbola as the defining conic section rather than a circle. They are defined as:

- Hyperbolic sine:
- Hyperbolic cosine:
- Hyperbolic tangent:
- Hyperbolic cosecant:
- Hyperbolic secant:
- Hyperbolic cotangent:
