I might be able to help. I think I know what it is saying. Do you have any ideas?

anonymous · Answer

well do I find the right middle and left side under the curve?

theeric · Answer

I think you want to break the $[0,\ 1]$ interval into $4$ sections, and you want to make rectangles in those sections so that the midpoint of the rectangle's top (or bottom) intersects the curve. Do you know what I mean?
