For example, instead of seeing something like > integrate from -oo to oo e^(-x^2) w/resp to x some users input a beautifully typeset version of this. How can I include such typeset mathematics in my own posts? $$\lim_{\stackrel{h\rightarrow0}{h\in\mathbb R}}$$Sun, 22 Jun 2014 18:56:58 -0500http://calc3.askbot.com/question/9/how-can-i-include-typeset-mathematics-in-my-posts/http://calc3.askbot.com/question/9/how-can-i-include-typeset-mathematics-in-my-posts/?answer=10#post-id-10Typeset input is entered into AskBot using LaTeX snippets which is then rendering using a JavaScript program called MathJax. For example, to input the integral mentioned in the question and indicate it's value is $\sqrt{\pi}$, you could input the following: $$\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}$$ This is then rendered as follows: $$\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}$$ Note that the double dollar signs ($$) are used to delimit the LaTeX input; everything between the double dollar signs are the LaTeX command that lead to the typeset expression. Use of *double* dollar signs indicate that the expression should be set on it's own line in *display mode*. You can use single dollar signs to include a simple math expression inline. For example, $\sqrt{\pi}$ by itself is input as $\sqrt{\pi}$ LaTeX itself is a huge system that can be used to create large documents - but you need only use small snippets for this site. This is actually a gentle way to get started with this valuable tool, anyway! There is plenty of information on LaTeX available online. A great tutorial for using the MathJax version of LaTeX is available [here](http://meta.math.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference).Sun, 22 Jun 2014 18:58:01 -0500http://calc3.askbot.com/question/9/how-can-i-include-typeset-mathematics-in-my-posts/?answer=10#post-id-10
