How do I type mathematics notation in my post?

Find the  \(\sum {} \) symbol on the editor toolbar; this is what you'll use to write mathematics in your posts. Simply click it and type mathmatics tex or latex codes in the dialog box that opens. In the case that you want to quickly type the code yourself without using this  \(\sum {} \) dialog box, use

 \[your-code-here\]

to wrap your code. If your math expression will be part of a sentence, use the paranthesis instead with the backslashes

\(your-code-here\)

The latex code for some common math symbols that we'll need for our class discussions is written below.

\[\le\]

 \le

\[\ge\]

 \ge

\[\pm\]

 \pm

\[\to\]

 \to

\[\infty\]

\infty

\[\pi\]

\pi

\[\theta\]

\theta

\[\left| a \right|\]

\left| a \right|

\[\left(a \right)\]

\left( a \right)

\[\frac{a}{b}\]

\frac{a}{b}

\[\sqrt a\]

\sqrt a

\[\sqrt[n]{x}\]

\sqrt[n]{x}

\[{a^n}\]

{a^n}

\[\mathop {\lim }\limits_{x\to \infty}\]

\mathop {\lim }\limits_{x \to \infty }

\[\frac{{dy}}{{dx}}\]

\frac{{dy}}{{dx}}

\[f'\]

f'

\[f''\]

f''

\[\sum\limits_{i=1}^n{3x}\]

\sum\limits_{i = 1}^n {3x}

\[\int{f(x)dx}\]

\int {f(x)dx}

\[\int\limits_1^2 {f(x)dx}\]

\int\limits_1^2 {f(x)dx}

\[\frac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}\]

\frac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}

\[\left[ {0,1} \right]\]

\left[ {0,1} \right]

 

As you learn mathematics further, you will need many new symbols and to type these in the forums you will need to learn more math tex codes. There is a nice website (www.hostmath.com) that helps in this regard.



I recommend memorizing some codes because it is just quicker to write mathematics online with the knowledge of the codes and without the need to transfer information from a different site. Nonetheless, this website is really helpful as you learn.
