- Converging means something is approaching something. Diverging means it is going away. So if a group of people are converging on a party they are c...
- (-1)^(n-1) does equal (-1)^(n+1) for every n value. Both equations oscillate every other N, every (-1)^ to an even number equal(-1)^ to a different...
- Suppose we want to know the limit of a^b as x goes to infinity, where a and b are both functions of x. If we find that a approaches 1 and b approac...
- I'll assume `{B(n)}` is a sequence of real numbers (but a sequence in an arbitrary metric space would be just as fine). `a)` `{B(n)}` has no limit...
- A sequence is a set of numbers. If it is convergent, the `value` of each new term is approaching a number A series is the sum of a sequence. If it...
- It is an alternating harmonic series. The signs change in every other term.
- It's completely arbitrary. Both 𝑛 – 1 and 𝑛 + 1 are valid here (as they are both odd when 𝑛 is even and vice versa) and there is no "convention"...
- We want 𝑎(𝑛) to be positive for odd values of 𝑛, and negative for even values of 𝑛. (−1)^𝑛 is negative for odd values and positive for even va...
- No. Not all functions approach a number as their input approaches infinity. One of the main things a function has to do to approach a number is to...
16 de nov. de 2022 · Eventually it will be very simple to show that this series is conditionally convergent. In this section we will discuss in greater detail the convergence and divergence of infinite series. We will illustrate how partial sums are used to determine if an infinite series converges or diverges.

There are numerous trends and tools in the world of economics and finance. Some of them describe opposing forces, such as divergence and convergence. Divergence generally means two things are moving apart while convergence implies that two forces are moving together. In the world of economics, finance, and trading, divergence and convergence are te...
When the value of an asset, indicator, or index moves, the related asset, indicator, or index moves in the other direction. This is what is referred to as divergence. Divergence warns that the current price trend may be weakening, and in some cases may lead to the price changing direction. Divergence can be either positive or negative. For example,...
The term convergence is the opposite of divergence. It is used to describe the phenomenon of the futures price and the cash price of the underlying commoditymoving closer together over time. In most cases, traders refer to convergence as a way to describe the price action of a futures contract. Theoretically, convergence happens because an efficien...
Technical traders are much more concerned with divergence than convergence, largely because convergence is assumed to occur in a normal market. Many technical indicators commonly use divergence as tools, primarily oscillators. They map out bands (both high and low ones) that occur between two extreme values. They then build trend indicators that fl...
31 de oct. de 2023 · The notions of convergence and divergence capture this behavior, acting as the gatekeepers between the finite and the infinite. This guide embarks on a journey through these concepts, illuminating the intricacies of convergent and divergent series and their pivotal role in a multitude of mathematical and real-world applications.

CONVERGENCE VS. DIVERGENCE A fortiori, 1 ≤. j 1. 2, so. j(j+1) N. N. −1. 1. S. N. ≤ , j. 2 j=1,3,5,... which we know converges. If on the other hand N is odd, then S. N = S. N−1 + N 1 +1. Both terms S. N. and 1/(N+ 1) are converging sequences, so their sum converges as well. This proves convergence. Note that the series converges to. 1 ...
Remember that a sequence is like a list of numbers, while a series is a sum of that list. Notice that a sequence converges if the limit as n approaches infinity of An equals a constant number, like 0, 1, pi, or -33. However, if that limit goes to +-infinity, then the sequence is divergent.
