**Math Calculus**

You could use the Trapezium Rule and then use Richardson Extrapolation to extrapolate to zero step size. If the step size is very large you need to use extrapolation using rational functions, like Pade approximants to do the extrapolation.

**algebra**

also, if you have a chart the x values in the chart represent the data range used for interpolation while anything lower than the min x value will be extrapolation and any term higher than the max x value will be extrapolation.

**Math - extrapolation**

The forward difference formula can be expressed as : f'(x0) = (1/h)[f(x0+h)-f(x0)]-(h/2)f''(x0)-(h^2/6)f'''(x0)+O(h^3). Use extrapolation to dervive an O(h^3) formula for f'(x0)
