Question

Use the definition of a definite integral (using right end points) to evaluate the integral.. Ive gotten to a certain point and im kinda confused.. (ill type what i have so far below!!).

Answer 1

\[\int\limits_{0}^{2}(x^2+x)dx =\lim_{n \rightarrow \infty} \sum_{i = 1}^{n} f \frac{2}{n}(\frac{2i}{n})\]\[\lim_{n \rightarrow \infty} \frac{2}{n} \sum_{i=1}^{n}[(\frac{2i}{n})^{2} + \frac{2i}{n}]\] \[\lim_{n \rightarrow \infty}\frac{2}{n} \sum_{i=1}^{n}[\frac{4}{n^2})i^2 + \frac{2}{n}i]\] \[\lim_{n \rightarrow \infty}[\frac{8}{n^3} \sum_{i=1}^{n}i^2 + \frac{4}{n^2} \sum_{i=1}^{n}i]\]

Answer 2

Any ideas?? :/

Answer 3

o my god... what math is this?

Answer 4

Calc 1

Answer 5

im taking pre cal next semester... i hope its not this complex
