Talk:Fundamental Theorem of Calculus

Does the lower bound of the first part have to be $a$ of the interval, or can it be any constant$\in [a..b]$? Or does such a distinction not matter, because we can always pick a subset of the interval? --GFauxPas 07:53, 17 January 2012 (EST)
 * The constant you can always add to an indefinite integral originates at least partly from this free choice of $a$. However, in this particular case, $a$ is convenient, as it means that swapping the bounds with a minus sign is not necessary. --Lord_Farin 07:59, 17 January 2012 (EST)

I’m confused by the fact this is marked as a candidate for Proof of the Week when the page has no proof on it? — Timwi (talk) 12:37, 3 December 2012 (UTC)
 * Click on the names "first part" and "second part" to get to the actual proofs. However, since the POTW mark has been added, each part has been given an additional proof, so I'm not sure it's okay to have a POTW candidate on the theorem rather than on one of the proofs --GFauxPas (talk) 12:41, 3 December 2012 (UTC)
 * I found out about clicking on the headings by now. Personally, I find that to be highly unintuitive... as regards to UI/UX design, perhaps there should be a separate link labeled something containing the word proof at the end of each part? — Timwi (talk) 12:44, 3 December 2012 (UTC)
 * Oh dear. That was me again. Sorry. --prime mover (talk) 14:44, 3 December 2012 (UTC)
