Area Estimate Under a Function
Question #4 (Medium): Limit for the Area Estimate Under a Function
Usually, when a graph or a dataset is given, number of rectangles ( ) for the area estimation is fixed.
But instead, when a function is given and asks to estimate the area under the curve, assume that
and use the limit expression:
Thus, ∑ , where .
First, establish the input variables needed for the limit expression:
