The '''hyperbolic trigonometric functions''' are analogs of the standard trigonometric functions using a hyperbola rather than a circle. They are defined as:
The '''hyperbolic trigonometric functions''' are analogs of the standard [[trigonometric function]]s using a [[hyperbola]] as the defining [[conic section]] rather than a [[circle]]. They are defined as:
*Hyperbolic sine: <math>sinh(x) = \frac{e^x - e^{-x}}{2}</math>
*Hyperbolic sine: <math>sinh(x) = \frac{e^x - e^{-x}}{2}</math>
