if you got the left one, why is the right one that much different. by the way the 2 means you made 2 subintervals right? so you have 2 rectangles.

so you let

for the LEFT(2) you chose the height of your two rectangles to be and , where

so for the RIGHT(2), do pretty much the same thing, except choose and for the height of your rectangles. - October 8th 2008, 06:36 PMamiv4
