f′′(x) = [f(x − h)−2f(x) + f(x + h) ]/h^2 − [(h^2/12)* f^(4th derivative) (z)]
where, x − h < z < x + h.
Suppose that the function values in the formula in the figure above contain round-off errors that are bounded in absolute value by A and that
|f^(4)(z)| ≤ M, x−h < z < x+h.
Derive a bound for the total error in terms of A, M and h....
Thanks for the help...
