Reimann Sum Help
Use the limit process to find the area of the region between the graph of the function and the x-axis over the indicated interval.

y = x^2 + 2 [0, 1]

Ans: 7/3

Can someone show me a step by step guide? Thanks!

It's $\underset{n\to \infty }{\mathop{\lim }}\,\frac{1}{n}\sum\limits_{i=1}^{n}{\left\{ {{\left( \frac{i}{n} \right)}^{2}}+2 \right\}}$ for $\Delta x=\frac{1}{n}$ and ${{x}_{i}}=\frac{i}{n}.$

Can you do that?
