Directions for inserting equations into your posts:
All symbols and such are here and here. I think a lot of these work as well.
Make sure you start the equation with a $ sign followed by “latex”. Then end your equation with a $ sign. So it looks like this when you are filling out your post…(Dollarsignlatex equation here Dollarsign).
$\textstyle \sum_{i=1}^n i^2$ Will Give you:
For example writing $\lim_{x\to c}\frac{f(x)-f(c)}{x-c}$ will give you an inline math formula
$\begin{pmatrix}a&b&c&d&e\\f&g&h&i&j\\k&l&m&n&0\\p&q&r&s&t\\u&v&w&x&y\end{pmatrix}$
To produce:
I’ve used the [WordPress Shortcode Syntax](http://codex.wordpress.org/Shortcode_API).
You may alternatively use the following equivalent syntax reminiscent of LaTeX’s inline
math mode syntax.
Can I change the color of the images produced?
Yes. You can set the default text color and background color of the images in the
Plugins -> WP LaTeX admin page.
You can also change the colors on an image by image basis by specifying `color`
and `background` attributes inside the LaTeX shortcode. For example:
[.latex color=”ff0000″ background=”00ff00″]e^{\i \pi} + 1 = 0[./latex] (remove periods)
will produce an image with a bright green background and a bright red foreground color.
Colors are specified in RGB with the standard 6 digit hex notation.
like this:
Can I change the size of the image?
You can specify a `size` attribute in the LaTeX shortcode:
[.latex size=”4″]e^{\i \pi} + 1 = 0[./latex] (remove periods)
Will make:
or, equivalently, an `s` parameter after the LaTeX inline syntax:
$.latex e^{\i \pi} + 1 = 0&s=4.$ (remove periods) Will give you the same thing.
The size can be any integer from -4 to 4 (0 is the default). These numbers correspond to
the following LaTeX size commands.
`
size = LaTeX size
-4 \tiny
-3 \scriptsize
-2 \footnotesize
-1 \small
0 \normalsize (12pt)
1 \large
2 \Large
3 \LARGE
4 \huge
Posting Tips:
Whenever you want to make make use of division or powers, or any equation that requires grouping terms together remember to wrap the group in { group } and put a slash (\) before each item. For example, e^{\i \pi} will produce 
What about schematics?
Add schematics to your post by inserting an image of the schematic.
Happy posting 🙂
