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

Sin^2(o)+cos^2(o) | 1 |

Tan^2(0)+1 | sec^2(0) |

cot^2(o)+1 | csc^2(o) |

Sin(s+t) | Sin(s)Cos(t)+Cos(s)Sin(t) |

Sin(s-T) | Sin(s)Cos(t)-Cos(s)Sin(t) |

cos(s+t) | Cos(s)cos(t)-Sin(s)sin(t) |

Cos(s-t) | cos(s)cos(t)+Sin(s)SIn(T) |

tan(s+t) | (Tan(s)+Tan(t))/(1-(Tan(s)tan(t)) |

tan(s-T) | (Tan(s)-Tan(t))/(1+(tan(s)Tan(t)) |

Sin(2O) | 2Sin(o)Cos(o) |

Cos(2O) | Cos^2(O)-Sin^2(O) |

Tan(2O) | (2Tan(O))/(1-Tan^2(O)) |

Sin(O/2) | +or- √((1-cos(O))/2) |

Cos(O/2) | +or- √((1+cos(O))/2) |
