comment How can I count waypoints between a curve?
What form does the curve between A and B take? Is it a straight line, an arc of a circle, a cubic spline (the last two will require additional 'control points' to be specified - what are they?) or something else?

Do you mean $a_i$ wherever you have $u_i$ (or vice versa)?

comment Calculate area under a curve
Yes, you are right. You can see that it works by looking at the plot. As for an explanation of why it works...

comment Counting words of varying length made out of a restricted alphabet
$n$ is the number of symbols (a, b, c, ...) and $y$ is the maximum word length you are considering. So for symbols (a,b) and words of length two or less, you have $n=2$ and $y=2$. Here $i$ is a dummy variable used for the summation.
