Taylor Remainder Formulas
Every smooth function f has Taylor polynomials
f (n) (a)
= f (a) + f (a)(x a) +
(x a)2 + +
(x a)k .
For example, the simplest Taylor polynomials are the constant function T0 (x) =

16. Inverse Functions. Let f be a one-to-one dierentiable function. Then
f has an inverse, which is continuous since f itself is continuous. Given a
point y in the domain of f , let x = f (y). Then y = f 1 (x).
