Approximating the Area under a Curve
The slider for the number of rectangles adjusts how many rectangles that are going to be used to approximate the area under the curve.
As the rcetangles become successively narrow the model uses an increasingly larger number of rectangles to approximate the area under the curve. 1. How accurate do you think the estimate of the area is with these left rectangles? 2. Is this an over or an underestimate?
