these two questions are confusing for me i dont know where to get started.
1.if n inscribed rectangles were used, what would the expression be, in sigma (http://s0.wp.com/latex.php?latex=%5C...&fg=333333&s=0) notation, that approximates the exact area? How is the value of this approximation related to the exact area of n approaches infinity?
2. Integrate the following:

This question seems to be taken out of context. Inscribed into what? It would help to post the complete question, including the information leading to it.
