Taylor series help approximate the value of a definite integral for a function whose antiderivative is hard to find. This article explains the key ideas behind Taylor's Theorem and an example of approximating its value with a polynomial function.

This article gives an introduction to calculus, starting with the concept of a function and how calculus helps us solve problems related to determining tangents to curves (expressed as functions), finding the minima/maxima like determining the maximum range of a projectile, and finding the length of curves, areas, and volumes.
