# 1/cotx

Input |
---|

1/(cot(x)) |

Result |

tan(x) |

Alternate form assuming x is real |

(sin(2 x))/(cos(2 x) + 1) |

Roots |

x = pi n, n element Z |

Series expansion at x=0 |

x + x^3/3 + (2 x^5)/15 + O(x^6) (Taylor series) |

Derivative |

d/dx(1/(cot(x))) = sec^2(x) |

Indefinite integral |

integral tan(x) dx = -log(cos(x)) + constant |
