We apply Action-Process-Object-Schema (APOS) Theory to pose a preliminary genetic decomposition (GD), conjecturing mental constructions that students would need to relate Riemann sums to integrals of functions of two variables over rectangles. The genetic decomposition is informed by the researchers' ...

The following theorem is stated: Given a sequence of real numbers a n , let f(x)=a [1/x] and consider the sequence of Riemann sums B n =(1/n)∑ k=1 n f(k/n)· If B=lim n→∞ B n exists, then lim →0 ∫ 1 f(x)dx=B· The theorem is proved for a wide class of...

However I didn't find any bounds on error of double integrals. How can I choose δxδx and δyδy such that: ∣∣∣∣∫a0∫b0f(x,y)dxdy−∑n=1K∑m=1Jf(nδx,mδy)δxδy∣∣∣∣≤ϵ|∫0a∫0bf(x,y)dxdy−∑n=1K∑m=1Jf(nδx,mδy)δxδy|≤ϵ for a ...
Approximating Definite Integrals as Sums 1.Let f(x)=4x+5. Estimate the area under f(x) on the interval { 0 \leq 7 } using 100 rectangles and a right hand rule. 2.let { f(x)=x^2+3x+1 }.Estimate t Evaluate the left, right, and midpoint Riemann sums for f(...
found using rectangles with the only difference being the height of the rectangles they use. All of the types of Riemann sums use the same interval and same widths of the rectangles but use different heights found at different parts of the integrals. Left Riemann sums use heights, or f(...
