I love electronics, designing my own devices and learning all the time. I also like programming, specially Android apps and microcontrollers. Currently I program in Java, C, a little of C++ and I'm learning Python.

I am from Argentina and currently studying Electronic Engineering at UTN San Francisco University.

Yes, I think I can do that but I only have one vector, whats is the other vector $v$ ?

Shouldn't be each points $iΔx$ for the right point and $(i-1)Δx$ for the left one instead $\frac{i}{n}$ ? I don't understand that :/ By the way very nice explanation :)

Thank you :) I understand what you are saying. But my $f(x) = \sqrt{x}$ That's why I don't understand why it is $\frac{i^2}{n^2}$ unless my book had an error. I understand that Riemann is: $$\sum_{i=1}^n f(C_i)Δx$$ But the divisions in n intervals of the funtion are not neccessarily equal.

$C_i$ is each point on the x axis. $C_i(right)$ is the right point of a rectangle and $C_i(left)$ is the left point

$f(x)=\sqrt{x}$
