Some MathJax Math

MathJax lets you employ $$\TeX$$ and $$\LaTeX$$ in web pages to render mathematics. Yay!

Inline $$\TeX$$ mathematics uses the delimiters $$x^2/y^2 = \mathrm{aarghh!}$$.

Display mathematics uses the standard $$\LaTeX$$ delimiters. $\frac{\int f(x) dx}{\int f(x)\cdot g(x) dx}$ or $$\sum_{n=0}^{\infty} \frac{1}{n!}x^n.$$ or $$\int_{-\infty}^{+\infty} \hspace{-1em} dx f(x)$$

Do I need $$\TeX$$ delimiters when loading environments? Does not appear so. \begin{eqnarray*} f(z) = \frac{1}{2\pi i}\int_{\mathcal{C}} \frac{f(z')}{z-z'} dz. \end{eqnarray*}

Here was the clue how to set up left alignment of equations. (And, in passing, a pointer to the MathJax-users Google group.)

Sample $$\TeX$$ macros: $$\RR$$. $$\caltxt{TESTIFYZ}$$ vs. $$\mathcal{TESTIFYZ}$$ $$a \newrel b$$ $$a \newrelz b$$ $$\bold{test}$$
