When a power series S_ is an antiderivative of a geometric series S_, we can find the function represented by S_ by integrating the expression for S_.Practic. That is different from any other kind of series that we've looked at to this point. This will not change how things work however. The first thing to notice about a power series is that it is a function of x x. In all the prior sections we've only allowed numbers in the series and now we are allowing variables to be in the series as well. For example, we can use them to define transcendental functions such as the exponential and. Power series are one of the most useful type of series in analysis.

A power series $\displaystyle\sum_{n=0}^\infty c_n x^n$ can be thought of as a function of $x$ whose domain is the interval of convergence. This is extremely valuable; for example, $e^x$ can be expressed as a power series, which is really just an infinite polynomial. Functions as Power Series. Conversely, many functions can be expressed as power series, and we will be learning various ways to do this. Power series are useful in mathematical analysis, where they arise as Taylor series of infinitely differentiable functions. In mathematics, a power series (in one variable) is an infinite series of the form where an represents the coefficient of the n th term and c is a constant. Multisummability is a method which, for certain formal power series with radius of convergence equal to zero, produces an analytic function. About this book. .
