Chapter VIII SOME SPECIAL FUNCTIONS. Rudin [Principle of Math Analysis]
POWER SERIES

In this section we shall derive some properties of functions which are represented by power seires
$\displaystyle{ f(x) = \sum_{n=0}^{\infty} c_n x^n \tag{1}}$
or, more generally,
$\displaystyle{ f(x) = \sum_{n=0}^{\infty}c_n (x -a)^n. \tag{2}}$
These are called analytic functions.

We shall restrict ourselves to real values of $x$ hence we shall encounter intervals of convergence instead of circles of convergence (see Th.3.39)
