key term - N

Definition

In a Riemann sum, "n" represents the number of subdivisions or rectangles used to approximate the area under a curve. It determines how accurate our estimation will be, with larger values of "n" providing more precise results.

Related terms

Delta x: Delta x (Δx) represents the width or length of each subdivision in a Riemann sum. It's calculated by dividing the interval length by "n".

Midpoint Rule: The midpoint rule uses midpoints within each subdivision to calculate function values in a Riemann sum, resulting in more accurate approximations.

Definite Integral:

The definite integral is the exact value of the area under a curve, which can be found using limits and calculus. It serves as a reference point for comparing Riemann sum approximations.
