• Using WYSIWYG Equation editor and Mathtex3.js for Beginner User

Creating LaTeX renderer for Blogger
For inserting an equation to a posting in a simple way, we need to make sure that LaTeX code can be rendered in the blog. Please follow the steps bellow:

- Copy (to clipboard) the following script using block and ctrl-c


- Add a HTML/Script footer Gadget by accessing your Dashboard and choose Layout>>Page Element, and then click the hyperlink Add a Gadget in the bottom of the layout, followed by selecting HTML/JavaScript gadget. In the popup windows paste the script which is copied before, so that it is like the picure bellow:
Click save with out typing any title. Then save the Page Elements.

Creating WYSIWYG Equation Editor 
Latex code is quite complex to remember because it is like programming script. Since we prefer works in the GUI environment, we need WYSIWYG (What You See Is What You Get) Equation Editor. The steps bellow will show you how to make a Blogger Gadget for equation editor:
- Copy the following script:

- Add a HTML/Script footer Gadget by accessing your Dashboard
- Paste the copied script in the content, and you can give Equation Editor as the Title.
- Save the gadget and the Page Elements.

Inserting LaTeX code in a Posting
Because the equation editor is not embedded in the posting editor, we should keep the page contained it and open a new window/tab for creating/editing a posting. Then follow these steps:
- Open Equation Editor by clicking the Lauch Editor link.


- Create an equation by click the symbol or samples of equation





- Click Copy to Document, the the windows will directly change to the main page where the equation editor gadget is.

- Copy the code from the box by blocking and copying
- Paste the code to the posting editor either in Compose or Edit HTML mode.
- Publish your post
\[ x = a_0 + \frac{1}{a_1 + \frac{1}{a_2 + \frac{1}{a_3 + a_4}}}\]

• Using Mathtex3.js for Advanced User 

Basically all the code can be used in a posting after adding a HTML/Script footer Gadget containing Mathtex3.js. You may read Short Math Guide for LATEX  for looking up the type set.Here some example codes:

\frac{{\displaystyle\sum\nolimits_{n> 0} z^n}}{{\displaystyle\prod\nolimits_{1\leq k\leq n} (1-q^k)}}

\[\frac{{\displaystyle\sum\nolimits_{n> 0} z^n}}{{\displaystyle\prod\nolimits_{1\leq k\leq n} (1-q^k)}}\]

V = \frac{k_2{[E]}+{[S]}}{K_m + {[S]}}}
\[V = \frac{k_2{[E]}+{[S]}}{K_m + {[S]}}\]

6CO_2 + 6H_2O \xrightarrow{Light Energy} C_6H_{12}O_6 + CO_2 \ \delta G^{\circ} = +2870kJ/mol
\[6CO_2 + 6H_2O \xrightarrow{Light Energy} C_6H_{12}O_6 + CO_2 \ \delta G^{\circ} = +2870kJ/mol\]

Inserting LaTeX using <img src="http://www.codecogs.com/gif.latex?copy_paste_here"/> should be treated as image because we use image tags for HTML ( <img .../>).

We can use LaTeX source from another WYSIWYG LaTeX editor and copy-paste into blog or Forum in HTML mode. Follow the steps bellow:

Because we use external WYSIWYG equation editor, then it is not embedded in the posting editor, we should open the equation editor and the entry blog/posting editor in the different windows/tabs. Then follow these steps:
1. Open WYSIWYG Equation Editor in a new window/tab.


2. Create an equation by click the symbl or samples of equation

3. Click Copy to Document, the the windows will directly change to the page where the WYSIWYG equation editor is.
4. Copy the code from the box by blocking and copying
5. Paste the code to the posting editor either in Compose or Edit HTML mode.

6. Then you change to Rich Text mode again, and you will see:

7. If you come back to HTML editor and want to change the equation, you will see the script has been changed. It is recommended to repeat the steps 1-6.
