SUMMARY

The discussion centers on the limit of the expression (1 + 1/n)^n as n approaches infinity, which converges to the mathematical constant e (approximately 2.718). Participants clarify that applying the limit inside the brackets is incorrect and emphasize the use of the binomial theorem to expand the expression. The final conclusion is that the limit evaluates to e, demonstrating a fundamental concept in calculus related to exponential growth.

PREREQUISITES
  • Understanding of limits in calculus
  • Familiarity with the binomial theorem
  • Basic knowledge of exponential functions
  • Experience with the concept of convergence in sequences
NEXT STEPS
  • Study the binomial theorem in detail
  • Learn about the derivation of the constant e
  • Explore the concept of limits and continuity in calculus
  • Investigate applications of the ratio test in series convergence
USEFUL FOR

Students studying calculus, mathematics educators, and anyone interested in understanding limits and exponential functions.

The Attempt at a Solution



I came up with this answer and i don't know how to continue:

(1+1/n)^n

I understand I have to put in limit n -> infinty. But can i put the limit inside the bracket? So i will get an answer of 1 ?

So ultimately, the ratio test is inconclusive?

(1 + (1/n))n → e (≈ 2.718) as n → ∞.
 
How did you get that? Can you bring me through the steps?
 
It's a standard limit. Use the binomial theorem to expand (1 + (1/n))n, and then take the limit n → ∞. You should get

1 + 1 + 1/2! + 1/3! + ... = e
