# Hyperbola

## Hyperbola Formulas

Equation | `x^2 / a^2 - y^2 / b^2 = 1` | `y^2 / a^2 - x^2 / b^2 = 1` |
---|---|---|

Orientation | horizontal (opening left and right) |
vertical (opening up and down) |

Focal axis | x-axis | y-axis |

Axe non focal | y-axis | x-axis |

Distance Centre - Foyer | `c = sqrt(a^2+b^2)` | `c = sqrt(a^2+b^2)` |

Center - Foci distance | a | b |

Center - Directrix distance | `d = a^2/c` | `d = b^2/c` |

Focal distance (FF') | 2c | 2c |

Eccentricity | `e = c/a` | `e = c/b` |
