Using taylors theorem with remainder to give the accuracy of an approximation. Among the topics are damped simple harmonic motion, transverse wave motion, waves in more than one dimension, and nonlinear oscillation. Most calculus textbooks would invoke a taylor s theorem with lagrange remainder, and would probably mention that it is a generalization of the mean value theorem. The precise statement of the most basic version of taylor s theorem is as follows. In particular, they explain three principles that they use throughout but that students today may not be familiar with.

For x close to 0, we can write fx in terms of f0 by using the fundamental theorem of calculus. In mathematics, a theorem is a nonselfevident statement that has been proven to be true, either on the basis of generally accepted statements such as axioms or on the basis of previously established statements such as other theorems.

The one that follows, from james wolfe, a proof of taylors formula, american mathematical monthly, 60 1953, 415416, is appropriate. We will now discuss a result called taylors theorem which relates a function, its derivative and its higher derivatives. The proof of taylors theorem in its full generality may be short but is not very illuminating. The taylor polynomial and taylor series are obtained from a generalization of the mean value theorem. In calculus, taylors theorem gives an approximation of a k times differentiable function around a given point by a k th order taylor polynomial.

Math 312 lecture notes linearization warren weckesser department of mathematics colgate university 23 march 2005 these notes discuss linearization, in which a linear system is used to approximate the behavior of a nonlinear system. That the taylor series does converge to the function itself must be a nontrivial fact.
