# What are oscillating sequences?

## What are oscillating sequences?

In mathematics, the oscillation of a function or a sequence is a number that quantifies how much that sequence or function varies between its extreme values as it approaches infinity or a point.

What is an oscillatory series?

I believe that it is the same as an alternating series. If that is the case, then an oscillating series is a series of the form: ∞∑n=0(−1)nbn , where bn≥0 . For example, the alternating harmonic series. ∞∑n=1(−1)nn.

Can an oscillating sequence converges?

Oscillating sequences are not convergent or divergent. Their terms alternate from upper to lower or vice versa.

### What is oscillation in simple words?

Oscillation is the process of moving back and forth regularly, like the oscillation of a fan that cools off the whole room, or the oscillation of a movie plot that makes you laugh and cry. Oscillation is from the Latin word oscillare for “to swing,” so oscillation is when something is swinging back and forth.

What are the example of oscillatory motion?

Oscillatory motion is defined as the to and fro motion of the body about its fixed position. Oscillatory motion is a type of periodic motion. Examples of oscillatory motion are vibrating strings, swinging of the swing etc.

Is a periodic sequence convergent?

Since Lorentz  proved that every almost periodic scalar sequence is almost convergent, the result follows for vector sequences by theorem 2. 1. 1, 2.1. 3 and 3.1.

## Is every oscillating sequence bounded?

(a) Every oscillating sequence has a convergent subsequence. (c) The sequence (sn) defined by sn = n diverges to infinity, but does not oscillate, as a requirement for an oscillating series is that it be bounded. So if the term divergent, would allow for diverges to infinity, then, as stated, part c is false.

Is sequence convergent or divergent?

A convergent sequence has a limit — that is, it approaches a real number. A divergent sequence doesn’t have a limit. Thus, this sequence converges to 0. In many cases, however, a sequence diverges — that is, it fails to approach any real number.

Which is an example of an oscillating series?

For example, the series 1 + 1 – 1 + 1, 1… wavers between 2 and 1. More formally, we would say that the limit oscillates between 2 and 1. An oscillating series is considered to be divergent (or partially divergent), because it never reaches, or settles on a particular number (or limit).
