Hi, I'm just starting to learn integration (I went to the first class in my summer course yesterday), and I'm already a bit confused. I was doing some practice problems in the text, and I found this:(adsbygoogle = window.adsbygoogle || []).push({});

Find the most general antiderivative of f on the indicated interval:

[tex]f(x) = -\tan x[/tex] on [tex](-\frac{\pi}{2}, \frac{\pi}{2})[/tex]

I'm...really unsure as to how to do this problem. All this time I'm thinking, "What do I differentiate to get tan x in the first place?" ...heh, I'm still not sure. Could someone please give me some pointers? Thanks!
