APFIVE Definition of a Riemann Sum
Which of the following best describes a Riemann sum?
A
A Riemann sum computes the exact area under a curve by summing the areas of trapezoids.
B
A Riemann sum approximates the area under a curve by summing the areas of rectangles, and as the number of rectangles increases, the approximation approaches the exact value of the definite integral.
C
A Riemann sum represents the derivative of a function’s antiderivative at a specific point.
D
A Riemann sum always overestimates the area when using the left endpoints.
