Area Estimate Under a Function
Question #5 (Medium): Interpreting the Limit
This is same as Question #4 but working backwards.
Based on the limit expression:
1) Determine the interval from
2) Convert into a regular function notation without the subscript .
Find the functional region whose area is equal to the limit.
1) It looks like
, and since ,
fits the form of . So must be .
and since , then
, which means so .
So the interval is , ie.
Therefore, the limit
represents the area under the function over the
interval (ie. .
