    Proof
In summary, the conversation is about finding the value of the limit of a fraction using Riemann-integrals and upper/lower Riemann sums. It is suggested to find a particular integral to represent the limit as a Riemann sum.

Can anybody help me with the following:

[tex]\lim_{n \rightarrow \infty} = \frac{1^k+2+k+...+n^k}{n^{k+1}}=\frac{1}{k+1}[\tex]

How do you proof this equation with the Riemann-integral, especially with upper/lower riemann sums?

thank you!

Find a particular integral so that the fraction on the left-hand-side is the Riemann sum when the interval is divided into n equal parts. Then that limit is the value of the integral.
 

1. What is "Proof of a Sum_Integral"?

"Proof of a Sum_Integral" is a mathematical concept that involves using integration to prove that two functions are equivalent in a certain range.

2. How does "Proof of a Sum_Integral" work?

In "Proof of a Sum_Integral", the integral of two functions is taken and then compared to the sum of the same two functions. If the two results are equal, then it can be proven that the two functions are equivalent in that range.

3. What is the purpose of using "Proof of a Sum_Integral"?

The purpose of using "Proof of a Sum_Integral" is to provide a rigorous and mathematical way to prove that two functions are equivalent in a certain range. This can be useful in various applications, such as in physics and engineering.

4. Are there any limitations to "Proof of a Sum_Integral"?

One limitation of "Proof of a Sum_Integral" is that it can only be used to prove equivalence in a certain range. If the range is not specified, the proof may not hold. Additionally, it may not be applicable to all types of functions.

5. Can "Proof of a Sum_Integral" be used to prove inequalities?
