Ratio Test. Suppose we have the series ∑an ∑ a n. Define, if L < 1 L < 1 the series is absolutely convergent (and hence convergent). if L > 1 L > 1 the series is divergent. if L = 1 L = 1 the series may be divergent, conditionally convergent, or absolutely convergent. A proof of this test is at the end of the section.

A power series is basically an infinite series that is comparable to a polynomial with many terms. The power series will usually converge to a value “x” within a given period, such that the absolute value of x is less than some positive number “r,” which is known as the radius of convergence .

Sometimes we’ll be asked for the radius and interval of convergence of a Maclaurin series. In order to find these things, we’ll first have to find a power series representation for the Maclaurin series, which we can do by hand, or using a table of common Maclaurin series. An annuity can be defined as a series of fixed payments made to a recipient at equal intervals. Some examples of annuities include interest received from fixed deposits in banks, payments made by insurance companies and pension payments.If f(x) f ( x) is an analytic function for all x x, then the radius of convergence for 1/f(x) 1 / f ( x) is the distance from the center of convergence to the closest root (possibly complex) of f(x) f ( x).
