TeX formatting reference sheet

Here is a basic list of formatting tips for use on Philica. Enclose these codes between tags: so, for example, type $$y=x^2$$ to produce $y=x^2$Anything not covered below can be found online, for example on John Forkosh’s website and in the mathematic formulae section of this page.

Basic formatting

 Code You type You get ^ = superscript $$y=x^2$$ $y=x^2$ _ = subscript $$y=x_i$$ $y=x_i$ ^ and _ together $$y=x_i^2$$ $y=x_i^2$ \frac{}{} $$y=\frac{1}{x}$$ $y=\frac{1}{x}$ \left( and \right) $$y=\left(\frac{1-x}{x-1}\right)$$ $y=\left(\frac{1-x}{x-1}\right)$ \sum{} $$y=\sum{x_i}$$ $y=\sum{x_i}$ \sum{} with limits $$y=\sum_1^k{x_i}$$ $y=\sum_1^k{x_i}$ \prod{} $$y=\prod{x_i}$$ $y=\prod{x_i}$ \int{} $$y=\int{x_i}$$ $y=\int{x_i}$ \int{} with limits $$y=\int_{-\infty}^\infty{x_i}$$ $y=\int_{-\infty}^\infty{x_i}$
