It seems like you might be referring to "hyperbolic functions." Hyperbolic functions are analogs of the ordinary trigonometric functions but for a hyperbola rather than a circle. The primary hyperbolic functions are: 1. **Hyperbolic Sine** (\\(\\sinh\\)): \\\[ \\sinh(x) = \\frac\{e^x - e^\{-x\}\}\{2\} \\\] 2.
