## How are infinite series used in real life?

Infinite series have applications in engineering, physics, computer science, finance, and mathematics. In engineering, they are used for analysis of current flow and sound waves. In physics, infinite series can be used to find the time it takes a bouncing ball to come to rest or the swing of a pendulum to stop.

## Why is convergence and divergence important?

Convergent series goes to a finite specific value so the more terms we add the closer to this we get. Divergent series on the other hand does not, they either grow indefinitaly in some direction or oscillate, as such the addition of more terms will cause it change value drastically.

**Why is convergence of series important?**

If the series converges to a solution, then the answer is yes: you can get as good an approximation as you want to that solution by taking the sum of enough terms of the series. Convergence of series is exactly what is needed to put trigonometry on rigorous footings.

**How important is the knowledge of arithmetic series in your daily life as a student?**

The arithmetic sequence is important in real life because this enables us to understand things with the use of patterns.

### How important is the concept of series in real life?

We’ve seen that geometric series can get used to calculate how much money you’ve got in the bank. They can also be used to calculate the amount of medicine in a person’s body, if you know the dosing schedule and amount and how quickly the drug decays in the body.

### Why is it important for us to learn series and patterns?

Patterns provide a sense of order in what might otherwise appear chaotic. Researchers have found that understanding and being able to identify recurring patterns allow us to make educated guesses, assumptions, and hypothesis; it helps us develop important skills of critical thinking and logic.

**How are arithmetic series used in real life?**

Examples of Real-Life Arithmetic Sequences

- Stacking cups, chairs, bowls etc.
- Pyramid-like patterns, where objects are increasing or decreasing in a constant manner.
- Filling something is another good example.
- Seating around tables.
- Fencing and perimeter examples are always nice.

**What do you understand by convergent and divergent thinking and how does this enhance group creativity?**

It is a source of ideas, suggests pathways to solutions, and provides criteria of effectiveness and novelty. Convergent thinking is used as a tool in creative problem solving. Divergent thinking typically occurs in a spontaneous, free-flowing manner, where many creative ideas are generated and evaluated.

#### How do you know if a series is divergent or convergent?

If an infinite series has a limit, then it’s a convergent series. If it doesn’t, it’s a divergent series. A series will be convergent if the addends when n is very large are equivalent to zero. An infinite series is also convergent to a limit L if the summation of the partial sum of that same series is equal to the same limit L.

#### What is the infinite sum of Divergent Series?

If the aforementioned limit fails to exist, the very same series diverges. It’s denoted as an infinite sum whether convergent or divergent. The partial sums in equation 2 are geometric sums, and this is because the underlying terms in the sums form a geometric sequence.

**How do you prove an infinite series is convergent to a limit?**

An infinite series is also convergent to a limit L if the summation of the partial sum of that same series is equal to the same limit L. We can test for convergence in many ways: n -th term test, comparison test, ratio test, and Cauchy condensation test are a few of those.

**Why do series have to converge to zero to converge?**

Again, as noted above, all this theorem does is give us a requirement for a series to converge. In order for a series to converge the series terms must go to zero in the limit. If the series terms do not go to zero in the limit then there is no way the series can converge since this would violate the theorem.
