This is a geometric series with ratio | r | = |(-1)(3)| = | 3 | 1, therefore it will diverge. EXAMPLE 3: Write out the first few terms or the following series to show how the series starts. Then find the sum of the series. SOLUTION: Now to determine the sum of this series. To do this, I will split the original sum into a difference of two sums.

Concepts surrounding infinite series were present in ancient Greek mathematics as Zeno, Archimedes, and other mathematicians worked with finite sums. Zeno posed his paradox in about 450 BCE, and Archimedes found the area of a parabolic segment in approximately 250 BCE by determining the sum of the infinite geometric series with constant ratio 1

mc-TY-convergence-2009-1. In this unit we see how finite and infinite series are obtained from finite and infinite sequences. We explain how the partial sums of an infinite series form a new sequence, and that the limit of this new sequence (if it exists) defines the sum of the series. We also consider two specific examples of infinite series ...

Definitions. A function is called Holomorphic if it is complex-differentiable in the domain D. A function. is called Analytic if it has a convergent power series about some point. . A function has a Singularity at a point if it fails to be well defined at that point, or appears to “blow up” at that point. We also use some well-known results ...

If it converges, find its sum. SOLUTION: EXAMPLE 6: Find the values of x for which the geometric series converges. Also, find the sum of the series (as a function of x) for those values of x. SOLUTION: For this geometric series to converge, the absolute value of the ration has to be less than 1. r = (-1) x 2

One thus has a way to sum certain infinite series when the function F(n) corresponds to a Laplace transform of a function f(t) provided one can evaluate the integral on the right side of the equality exactly or evaluate it numerically faster than summing the original infinite series. Lets look at several examples. Consider first the infinite sum …
