Approximating an integral with rectangles whose heights come from the centre of each subinterval uses the:
AChain rule use
BProduct rule use
CTrapezoid rule
DMidpoint rule
Answer & Solution
Correct answer: D. Midpoint rule
1. The height is taken in the middle.
2. Rectangles are still used.
3. It is the midpoint rule itself.
