=Conventions?= Are there guidelines with respect to formatting of TeX for wikibooks? For example, should an example be done in display as opposed to inline math, as in $$\displaystyle\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

as compared to stating the same equation $$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$ inline, the former using \displaystyle?

I have noted that conventions vary from page to page (for example, in $$ax^2+bx+c=y$$ sometimes x and y are capitalized, sometimes, not, sometimes a,b,and c are capped, and sometimes not, and each time the convention is changed the student is left in a muddle.
