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' ...
[Please note that what we are about to do is the way computers find integrals numerically.] Riemann Sums Riemann Sums give us a systematic way to find the area of a curved surface when we know the mathematical function for that curve. They are named after the mathematician Bernhard Riemann ...
Riemann sums & definite integrals (4.3) November 10th, 2016 I. Riemann Sums Def. of a Riemann Sum: Let f be defined on the closed interval [a, b], and let be a partition of [a, b] given by where is the width of the ith subinterval. If is any point in the ith subinterval, th...
If you have a function you want to integrate, but you’d rather let a computer make a really close approximation then actually doing it by hand, then this app is for you. Riemann Sums uses Riemann’s summation techniques to compute integrals. After entering your function and range, press ...

In addition, we can also apply integration by parts on Riemann-Stieltjes integrals. Particularly, if we assume f has a continuous derivative and g is of bounded variation on [a,b], then \int_a^bf(x)\mathrm dg(x)=f(x)g(x)|_q^b-\int_a^bg(x)f'(x)\mathrm dx ...

When I studied for the actuarial exams, we used Riemann sums to approximate integrals by using a finite sum. This technique is still valid, though it’s not on the current exam syllabus. But Riemann’s most interesting work is in math theory.In my previous blog, I mentioned how...
