(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

This series is what dictates the graph above.

3. The attempt at a solution

I don't understand what's going on. If they're using the series that i pasted below then why aren't they multiply each value in the brackets by -2/pi?

I also don't get why terms in the brackets are

[(-2pi + 0) + f(-2pi - 0)]

Where did they come from? Where does 1/2 come from that multiplies the brackets. very confused.
