Interesting convergence of sequence

In summary, the conversation discusses a real sequence and its limit as n approaches infinity. The sequence is defined as a_n being between 0 and 1, with each term being the previous term minus the square of the previous term. The question asks if the limit of n times a_n exists, and if so, how to calculate it. The conversation also mentions the expectation of showing one's own solution before asking for alternative solutions.

Homework Statement


Let [itex](a_n)_{n\in\mathbb{N}}[/itex] be a real sequence such that [itex]a_0\in(0,1)[/itex] and [itex]a_{n+1}=a_n-a_n^2[/itex]
Does [itex]\lim_{n\rightarrow\infty}na_n[/itex] exist? If yes, calculate it.

Asking for a solution when you haven't shown your own goes against the general spirit of the homework help forum. Try another forum if you don't want to show your own proof.
 

Related to Interesting convergence of sequence

What is an "interesting convergence of sequence"?

An interesting convergence of sequence refers to a situation where a sequence of numbers or values appears to be approaching a specific limit or pattern. This can occur in various fields of science, including mathematics, physics, and biology.

What causes an interesting convergence of sequence?

The cause of an interesting convergence of sequence can vary depending on the field of study. In mathematics, it could be due to the properties of the numbers themselves, while in physics it could be the result of underlying physical laws. In biology, it could be a reflection of evolutionary processes.

How is an interesting convergence of sequence identified?

An interesting convergence of sequence is typically identified by observing a pattern or trend in a sequence of numbers or values. This can be done through visual analysis or by using mathematical or statistical techniques.

What is the significance of an interesting convergence of sequence?

An interesting convergence of sequence can have significant implications in its respective field of study. It can provide insights into the underlying principles and mechanisms at work, and may also lead to the development of new theories or applications.

Can an interesting convergence of sequence occur in real-life situations?

Yes, interesting convergence of sequence can occur in real-life situations. In fact, many real-world phenomena can be described and predicted by using mathematical and scientific principles, including the convergence of sequences.
