What can go Wrong?
Not every function is analytic. The video below explores the different ways in which a Taylor series can fail to converge to a function f(x).
- The function may not be infinitely differentiable, so the Taylor series may not even be defined.
- The derivatives of f(x) at x=a may grow so quickly that the Taylor series may not converge.
- The series may converge to something other than f(x).
