## Abstract

The decimal expansion $$\tfrac{1}{3} = 0.3333 \ldots$$ is a representation of $$\tfrac{1}{3}$$ as an infinite sum $$\tfrac{3}{{10}} + \tfrac{3}{{100}} + \tfrac{3}{{1000}} + \tfrac{3}{{10,000}} + \cdots$$. In this chapter, we will see how to represent numbers as infinite sums and to represent functions of x by infinite sums whose terms are monomials in x. For example, we will see that
$$\ln 2 = 1 - \frac{1}{2} + \frac{1}{3} - \frac{1}{4} + \cdots$$
and
$$\sin x = x - \frac{{{{x}^{3}}}}{{1 \cdot 2 \cdot 3}} + \frac{{{{x}^{5}}}}{{1 \cdot 2 \cdot 3 \cdot 4 \cdot 5}} - \cdots .$$
