Homework Help Overview

The original poster is exploring the limit as n approaches infinity for the expression (1 + 1/n)^n, recognizing it as the mathematical constant "e." They seek to transform this limit into a series to facilitate a proof, specifically comparing it to the infinite series sum from n=0 to infinity for 1/n!.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the possibility of finding a power series for a function and reference the Taylor series expansion. There is an attempt to express the limit in terms of a series, with some participants contributing thoughts on the structure of a Taylor series.

Discussion Status

The discussion is ongoing, with participants sharing insights about series expansions and Taylor series. There is no explicit consensus yet, but the conversation is moving towards understanding how to relate the limit to a series representation.

Contextual Notes

There may be constraints related to the original poster's understanding of series and limits, as well as the need to adhere to homework guidelines that discourage direct solutions.

I am looking for a method to express limit n goes to infinity for the quantity (1+1/n)^n ...I know and recognisee this as "e" , but i need to transform it into a series to prove it. I plan to compare the transformed limit expression to "sum from n=0 to n=infinity for 1/n! how can I re express this?

Do you know how to find a power series for a function?
 
not in full, but f(0)*(X-x0)+f(1)*(x-x0)/1!+f(2)*(x-x0)/2!...? yes?

The 1-dimensional Taylor series of a function centered at a point x0 in the domain is f(0)(x0)*(x-x0)/0! + f(1)(x0)*(x-x0)/1! + f(2)(x0)*(x-x0)/2! + ...
where f(i)(x0) is the ith derivative of f at x0. See Taylor series for more detailed analysis.
