Welcome to ProofWiki! Since you're new, you may want to check out the general help page. It's the best first stop to see how things are done (next to reading proofs, of course!). Please feel free to contribute to whichever area of mathematics interests you, either by adding new proofs, or fixing up existing ones. If you have any questions please feel free to contact one of the administrators, or post your question on the questions page.

Here are some useful pages to help get you started:

  • Community Portal - To see what needs to be done, and keep up to date with the community.
  • Recent Changes - To keep up with what's new, and what's being added.
  • Check out our house style if you are keen on contributing.
  • Main Page talk - This is where most of the main discussions regarding the direction of the site take place. If you have any ideas, please share them!

Stackexchange citations

Please see what I wrote here:

Talk:Derivative of Sine Function/Proof 5

and please try to understand our site philosophy. We do not disallow links for arbitrary reasons. It is a fact that material on the internet is ephemeral. Half an hour's browsing on Wikipedia, for example, and you will find that far too high a proportion of the external links are broken, referring as they do to pages that no longer exist (or have moved).

The same applies to sites like stack exchange. While one hopes that links are going to stay around for ever, there is no guarantee of this. It is possible that the entire site will up and move, and so a new URL will be needed for each and every page we link to on that site. Hence we request that all links to stack exchange are made via the template {{Stackexchange}}, so that if the format of the URLs change for any reason, all we have to do is change the template and all the pages invoking it will automatically update with it.

I alert you to house style, of course; note that the main nonconformance of the new page you added is its discursive style. We try to keep verbiage to a minimum. Unless something complicated really does need explaining in natural language it is a site convention that material consists of the mathematical steps in mathematical language, with the bare minimum of words to hold it together. --prime mover (talk) 19:34, 26 January 2019 (EST)

The material you're adding

A quick heads-up: basic results in integral calculus have more or less basically been done.

I see how you're trying to find a niche where you want to contribute something, but the area you're working in here is fairly well covered.

You might want to attack an area which still needs a fair amount of work. --prime mover (talk) 03:41, 29 January 2019 (EST)


Help I can not upload a new file! File uploaded always seems to be identical to old, even if I have changed the version on my hard disk! How do I delete bad uploads and upload a genuine new one! --Pelliott (talk) 09:05, 30 January 2019 (EST)

Yeah, seen this before. There's a bug somewhere. The new file is uploaded, but there's some undeleted cache somewhere that isn't getting refreshed. When you invoke the file on the page you include it on, change the size to a different |nnnpx and it will then force a new instantiation of it. --prime mover (talk) 09:10, 30 January 2019 (EST)

How do I make an internal reference, that is, a reference to another line in the proof I am currently writing?--Pelliott (talk) 13:10, 30 January 2019 (EST)

See examples of other proofs for examples. In an "eqn" template, the "n" parameter, for example, turns "n = 1" to $(1):$ and then all you need to do is say "From $(1)$, ..." or whatever.

I do not understand this, what is the "n" parameter and how do I specify it? --Pelliott (talk) 15:58, 30 January 2019 (EST)

Like any other parameter for a template. Use parameter n, set it to 1. Or whatever number. {{eqn}} Read it. I recommend you study some of the existing proofs on this site to get a handle on how we do things here.
If you're not in an eqn template, use :$(1): \quad$ at the start of the line, and use "From $(1)$" as before --prime mover (talk) 15:02, 30 January 2019 (EST)


I have been looking for this integral $\int\sqrt{a^{2}-x^{2}}dx$ and haven't been able to find it. I have found $\int\frac{1}{\sqrt{a^{2}-x^{2}}}dx$ it was listed as "Primitive of Reciprocal of Root of a squared minus x squared" but I could not find "Primitive of Root of a squared minus x squared"

Is it missing or am I looking in wrong place? Thank You --Pelliott (talk) 20:14, 30 January 2019 (EST)

Sorry, but I can't understand the question. What do you mean you "can't find it"? --prime mover (talk) 01:25, 31 January 2019 (EST)

Equations for Lines

I have added some of the material concerning equations of straight lines that you flagged up as missing. Please feel free to cite any of these results in any of the work you may subsequently do. --prime mover (talk) 17:46, 5 February 2019 (EST)
