1 2 3 | ```
deformula.moneone(f, upper, lower, ...,
zero.eps = 1.0e-12, rel.tol = 1.0e-8,
start.divisions = 8, max.iter = 12)
``` |

`f` |
an integrand function for integral. |

`lower, upper` |
the limits of integration. |

`...` |
additional arguments to be passed to <e2><80><98>f<e2><80><99>. |

`zero.eps` |
a threshold value to be zero. |

`rel.tol` |
a value for relative tolerance. |

`start.divisions` |
the initial number of divides. |

`max.iter` |
an integer for the maximum number of iterations to increase divides. |

returns a list with components;

`value` |
an value for integral. |

`x` |
a vector of subintervals. |

`w` |
a vector of weights. |

`t` |
a vector of subintervals for trapezoid integral. |

`h` |
a value of subinterval. |

`message` |
OK or a string for the error message. |
