    hello isabella

    Romberg integration is an application of Richardson’s extrapolation, using the Trapezoidal Rule as the fundamental method of approximation.

    One may present Romberg’s integration process in a lattice form, where the values in the first column are computed using the Composite Trapezoidal Rule and the remainder using Richardson’s extrapolation: that is by the formulae

    [tex]T_{2n}^{(k)} =\frac{4^kT_{2n}^{(k-1)}-T_{n}^{(k-1)}}{4^k-1}[/tex]

    then the last value in the lattice will give you an approximation to the area under the curve

    and for the monte carlo iv already explained it in your other post if you have have any problems, elaborate on what you have problems understanding
