The forward-difference formula can be expressed as f (x0) = 1 h [f (x0 + h) f (x0)] h 2
Chapter 4, Problem 8(choose chapter or problem)
The forward-difference formula can be expressed as f (x0) = 1 h [f (x0 + h) f (x0)] h 2 f (x0) h2 6 f (x0) + O(h3 ). Use extrapolation to derive an O(h3) formula for f (x0).
