Question | Answer |
---|---|

(P) Equation - Horizontal | (x-h)^2 = 4p(y-k) |

(P) Equation - Vertical | (y-k)^2 = 4p(x-h) |

(P) Standard Equation (horizontal) | ax^2 + by + c = 0 |

(P) facing up or to the right when _ and down and left when _ | positive - negative |

(P) Focus - horizontal - vertical | (h,k+p) - (h+p,k) |

(P) Directrix | y = k-p |

(P) Vertex | (h,k) |

(E) Equation - Horizontal | (x)^2/(a)^2 + (y)^2/(b)^2 = 1 (Always 1) |

(E) Equation - Vertical | (X)^2?(b)^2 + (Y)^2/(a)^2 = 1 (Always 1) |

(E) Vertices - horizontal - vertical | H = (h+-a,k) - V = (h,k+-a) |

(E) Foci - Hor - Ver | H = (h+-c,k) - V = (h,k+-c) |

(E) equation for c | c^2 = a^2 - b^2 |

(E) Eccentricity equation | e = c/a |

(H) Equation - Horizontal | (X)^2/(a)^2 - (Y)^2/(b)^2 = 1 (Always 1) |

(H) Equation - vertical | (Y)^2/(a)^2 - (X)^2/(b)^2 = 1 (Always 1) |

(H) Midpoint is the _ and is written _ | Center - (h,k) |

(H) Vertices - Hor - Ver | H = (h+-a,k) - V = (h,k+-a) |

(H) Foci - Hor - Ver | H = (h+-c,k) - V = (h,k+-c) |

(H) Asymptotes - hor - ver | (y-k) = (+-b/a)(x-h) - (x-h) = (+-b/a)(y-k) |

(H) Equation for c | c^2 = a^2 + b^2 |

(H) horizontal directrix is a _ equation | Y= |

(H) vertical directrix is a _ equation | X= |
