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!

## A few points on presentation

I hope you don't mind if I make a few stylistic recommendations, consistent with the house style :)

For displayed (indented) equations, write \ds at the beginning of the line. To see how these compare \sum_{n \mathop = 1}^\infty \frac {c_n} {n!} x^n renders as:

$\map f x = \sum_{n \mathop = 1}^\infty \frac {c_n} {n!} x^n$

without \ds as opposed to:

$\ds \map f x = \sum_{n \mathop = 1}^\infty \frac {c_n} {n!} x^n$

with \ds. Quite a bit nicer :) The eqn template adds this automatically, though there isn't really a need to include it if you're only "displaying" a single line.

Here, we try to use short sentences that are straight to the point. For example, "a result in combinatorics known as the exponential formula" is redundant. Writing "by the exponential formula", along with a link to the appropriate result, cuts a lot of the waffle. We also tend to include a line break after every sentence, to avoid ugly clumping.

For congruences, write a \equiv b \pmod c to produce $a \equiv b \pmod c$. However, be careful, because if you were to write for example a \equiv b \pmod 10, it will render as $a \equiv b \pmod 10$. Instead, when there is more than a single character after the pmod, write a \equiv b \pmod {10} to produce $a \equiv b \pmod {10}$.

Most of this feedback is for Power Series Expansion for Exponential of Cosine of x/Proof 2, but I've just had a look at Taylor Series of Logarithm of Gamma Function and saw that it is a lot nicer stylistically. I would however point out:

• You should specify the branch of logarithm when working with complex and negative arguments. (most results deal with the principal logarithm so this doesn't require much thought. Doesn't matter with results concerning derivatives because the branches only differ by a constant.).
• You should link some more results supporting your assertions. (no need to go over the top, but it makes it clear where steps come from)

This might seem like a lot but it seems that, looking at your most recent contribution, you're adapting to the style here quite well, so keep it up! Just thought I'd leave some pointers.

Hope this helped, feel free to ask any questions.

One further thing: if the work needed to tidy up your existing pages looks too daunting, you will find that if you leave it long enough, someone will go in and fix it up anyway. $\substack{. \ . \\ \smile}$ --prime mover (talk) 05:56, 23 April 2018 (EDT)
