# Example LaTeX page

This page shows how to include equation using LaTeX syntax in documents.

jsMath provides the ability to use LaTeX for math equations in Plone. While it does not provide full LaTeX it does provide a subset of math symbols and allows for positioning of equations.

All equations must be surrounded by

"$$" at the beginning and "$$"

A list of TeX Symbols supported by jsMath can be found here http://www.math.union.edu/~dpvc/jsMath/symbols/

Below are shown what must be entered in the editor page along with what it will look like when rendered.

1. $$\sqrt{\frac{x^2}{x+1}-2}$$
$$\sqrt{\frac{x^2}{x+1}-2}$$
2. $$\sum_{i=1}^n i = {n(n+1)\over 2}$$
$$\sum_{i=1}^n i = {n(n+1)\over 2}$$
3. Here is some inline math $$\int {1\over f}\,dx$$
Here is some inline math $$\int {1\over f}\,dx$$
4. \begin{align}(a+b)^3 &= (a+b)^2(a+b)\\&=(a^2+2ab+b^2)(a+b)\\&=(a^3+2a^2b+ab^2) +(a^2b+2ab^2+b^3)\\&=a^3+3a^2b+3ab^2+b^3\end{align}
\begin{align}(a+b)^3 &= (a+b)^2(a+b)\\&=(a^2+2ab+b^2)(a+b)\\&=(a^3+2a^2b+ab^2) +(a^2b+2ab^2+b^3)\\&=a^3+3a^2b+3ab^2+b^3\end{align}
5. $$\int^1_\kappa\left[\bigl(1-w^2\bigr)\bigl(\kappa^2-w^2\bigr)\right]^{-1/2} dw= \frac{4}{\left(1+\sqrt{\kappa}\,\right)^2} K\left(\left(\frac{1-\sqrt{\kappa}}{1+\sqrt{\kappa}}\right)^{\!\!2}\right)$$
$$\int^1_\kappa\left[\bigl(1-w^2\bigr)\bigl(\kappa^2-w^2\bigr)\right]^{-1/2} dw= \frac{4}{\left(1+\sqrt{\kappa}\,\right)^2} K\left(\left(\frac{1-\sqrt{\kappa}}{1+\sqrt{\kappa}}\right)^{\!\!2}\right)$$
6. $$\{ E=mc^{2}\}$$
$$\{ E=mc^{2}\}$$

### It even works in comments, enabling technical discussion!

$$C=\max_{p(x)} I(X;Y)$$
