Question:

Taylor’s formulaimage


expresses the value of ƒ at x in terms of the values of ƒ and its derivatives at x = a. In numerical computations, we therefore need a to be a point where we know the values of ƒ and its derivatives. We also need a to be close enough to the values of ƒ we are interested in to make (x - a)n+1 so small we can neglect the remainder.
