Finds roots of univariate functions by the usual Newton-Raphson (N-R) method.

`fun` |
a function for which the root is searched. |

`derf` |
a function which is the first derivative of the function to be solved. |

`x0` |
a numeric value to be used to start the algorithm. |

`eps` |
a numeric value to be considered as the tolerance for convergence of the algorithm. |

`maxit` |
a numeric value which denotes maximum number of iterations to be consumed. |

`silent` |
a logical statement which decides whether the iterations should be printed. |

`tun` |
a numeric value to decrease the steps |

`tun`

is used to decrease the N-R steps, since it sometimes might miss the root value by taking large steps. `tun=1`

corresponds to usual N-R.

Returns a numeric result of the root.
