I want to evaluate $\displaystyle \lim_{n \to \infty}$ for the following equation. $\displaystyle \frac{10e^{5n5}}{n}$ I wish to do so in order to calculate the definite integral. As $\displaystyle n \to \infty$, the numerator approaches 0 and the denominator approaches infinity. Therefore the limit is 0? This can't be correct as the definite integral I calculated was close to 1. Would I have to evaluate using partial sums?? Thank you in advance.

That limit is 0. What is the integral you are trying to solve?

Is $\displaystyle \frac{10e^{5n 5}}{n}$ the value at the nth point or the sum of the values of n terms?
