The goal of this section is to understand the meaning of such an infinite sum and to develop methods to calculate it. Since there are infinitely many terms to add in an infinite series, we cannot just keep adding to see what comes out. Instead, we look at the result of summing the first n terms of the sequences,
Convergence of an infinite series Consider an infinite series Let us define and so on . Then the sequence so formed is known as the sequence of partial sums (S.O.P.S.) of the given series. Convergent series: A series converges if the sequence exists. Also if of its partial sums converges i.e. if then is called as the sum of the given series .
Infinite Series Infinite series can be a pleasure (sometimes). They throw a beautiful light on sin x and cos x. They give famous numbers like n and e. Usually they produce totally unknown functions-which might be good. But on the painful side is the fact that an infinite series has infinitely many terms.
The Infinite Accumulation of a Constant is the series ∑ ∞ 1 , which diverges to infinity by the Definition of Convergence. n = 1 Various First-Logarithmic Series, ∑ ∞ n =2 1 /( n ⋅ (ln ( n )) p ) for various fixed real numbers p, converge for p > 1 and diverge otherwise, as is shown by the Integral Test.
Objectives In this lesson we will learn: the meaning of the sum of an infinite series, a formula for the sum of a geometric series, and to evaluate the sum of a telescoping series.
As we develop the theory of infinite sequences and series, an important application gives a method of representing a differentiable function ƒ(x) as an infinite sum of powers of x. With this method we can extend our knowledge of how to evaluate, differentiate, and integrate polynomials to a class of functions much more general than polynomials. We also investigate a method of representing a ...
SERIES AND PARTIAL SUMS What if we wanted to sum up the terms of this sequence, how many terms would I have to use? 1, 2, 3, . . . 10, . . . ? Well, we could start creating sums of a finite number of terms, called partial sums, and determine if the sequence of partial sums converge to a number.
A.1.2 Binomial Theorem for any Index In Chapter 8, we discussed the Binomial Theorem in which the index was a positive integer. In this Section, we state a more general form of the theorem in which the index is not necessarily a whole number. It gives us a particular type of infinite series, called Binomial Series.

Chapter 6 Infinite Series In the previous chapter we considered integrals which were improper in the sense that the interval of integration was unbounded. In this chapter we are going to discuss a topic which is somewhat similar, the topic of infinite series. An infinite series is a sum containing an infinite number of terms. For example,
The use of an analytic function to sum the series gives one an important clue for generating a myriad of other infinite series via a MacLaurin series expansions of certain functions F(x) whose series are evaluated at x=0 or some other chosen point.

Sequences The lists of numbers you generate using a numerical method like Newton's method to get better and better approximations to the root of an equation are examples of (mathematical) sequences.

The sum of an infinite series 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.
DEFINITION 1 If the limit of the sequence fSng exists we call it an INFINITE SUM of the sequence §n k=1 ak:
Infinite series are used in ordinary arithmetic in the form of decimal expansions. For example when we write 2/3 = 0.6666666... we are expressing the idea that the infinite series 0.666 L = 6 + 6 + 6 + L + 6 + L 10 100 1000 10k
