Definite Integrals

Example 1

Let f (x) = x2 on the interval [0,12]. How many rectangles must we use to guarantee that the right- and left-hand sums are within 100 of each other?

Example 2

Let f (x) = x2 on the interval [0,12]. How large must n be to guarantee that RHS(n) is within .5 of the exact area between f and the x-axis on [0,12]?
