For regular partition, the formula in my textbook is this.

[tex]x_k=a+k\Delta x, \text for k=0,1,2,...,n.[/tex]

My question is this, how does one find "k"? It is very important clearly!

$\Delta x = \frac{b-a}{n}$ where $[a,b]$ and n is the number of times you want to divide the interval.

The points in the partition will then be $a, a+\Delta x, a+2\Delta x,\ldots, a+(n-1)\Delta x, b$

Usually you are told how many times to divide the interval.
