Ex 3.2.4: Geometric Series mssing some words

[cbm755]

1. Go to http://www.math.ubc.ca/~CLP/CLP2/clp_2_ic/subsection-41.html
2. Expand the Example 3.2.4 Geometric series link.
3. The 3rd sentence is not parseable (by me at least)

I see:

Notice that we have chosen to start the summation index at n=0. That's fine. The first [2]

N={0,1,2,⋯}

while the notation

where [2] is footnote. Expanding that footnote I see:

Notice that we have chosen to start the summation index at n=0. That's fine. The first

It is actually quite common in computer science to think of 0 as the first integer. In that context, the set of natural numbers is defined to contain 0:

N={0,1,2,⋯}

while the notation

I guess this is trying to say "The set of integers is denoted by" or maybe "the first few integers define the Sequence of natural numbers". Honestly not sure.

hmm - the html from pretext is wrong... but pdf from the pretext is fine. sigh.
