    [SOLVED] three-point formula for numerical differentiation

    When using the three-point formulas for numerical differentiation, specifically for f'( x_0)= (1/2h)[-3f( x_0)+4f( x_0+h)-f( x_0+2h)]

    and f'( x_0)=1/2h[f( x_0+h)-f( x_0-h]

    When you have a list of different x and their value at f(x) when you go to plug the formulas in, and you get x_0 then you go to x_1 how does the formula change? like do all the x_0's get changed to x_1 and so forth? I got my first value done but now im getting stuck on the rest because I don't know what to do with the formula from here.
