# 1 tan2x

Input |
---|

1 tan(2 x) |

Result |

tan(2 x) |

Alternate form assuming x is real |

(sin(4 x))/(cos(4 x) + 1) |

Roots |

x = (pi n)/2, n element Z |

Series expansion at x=0 |

2 x + (8 x^3)/3 + (64 x^5)/15 + O(x^6) (Taylor series) |

Derivative |

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

Indefinite integral |

integral tan(2 x) dx = -1/2 log(cos(2 x)) + constant |
