Thread: Lagrage Error Bound Questions

So I've got my AP Calc test tomorrow and I feel fairly prepared, but I'd like some last minute input on this subject just to reassure myself.

The error of a Taylor series approximation of f(x) of n degrees must be at the most, the n+1 derivative of f(x) (at a point) divided by (n+1) factorial times the (absolute difference from where the series is centered)^(n+1).

What is this point where I find the n+1 derivative? Is it the max value of the n+1 derivative on the interval I'm estimating the error for?

This answered my questions enough.
