In this video we define R-S sums and provide the definition for R-S integral. We talk about the most simple case and provide a result functions which are R-S integrable with respect to a step function with a single step.

What is the difference between Riemann Stieltjes integral (defined using Riemann-Stieltjes sum) and Darboux Stieltjes integral (defined using upper darboux stieltjes sum and lower darbouxstieltjes sum )???
Or Are they equivalent ??

Great overview. What app are you using in this video?

Can anyone help to distinguish in the video here between instances of ε ( as in epsilon-delta notation) and ϵ (indicating membership) ?

let f be a real valued function define on [0 and 1]. such that, f(0) > 0, f(x) ≠ x for all x, and f(x) ≤ f(y). let a ={x: f(x) > x}. prove that sup a element of a and that f(x) > x
