A sufficiently differentiable function can be approximated near a point by a polynomial built from its derivatives at that point, the Taylor polynomial, with a remainder term that can be bounded explicitly. Named for Brook Taylor, it is the basis for power series expansions throughout analysis.
Facts
StatementTaylor's theorem states that a k-times differentiable function can be approximated near a given point by a polynomial of degree k, called the k-th order Taylor polynomial, built from the function's own derivatives at that point. 1 Classification
