I have a wordpress site and I would like to use some mathematical formulas (integral, derivative, summation, etc.) in some of the entries. Are there any references (I’ve already googled) that anybody knows about for doing this without resorting to creating them in an image and pasting them into a page?
Display mathematical symbols like integral or derivative in a web page?
Maybe you can try to use mathjax
Also use in http://math.stackexchange.com
See also http://meta.math.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference
You can directly use the wordpress extension http://wordpress.org/plugins/mathjax-latex/
The UTF-8 chararacter set includes many math symbols already.
Integral = ∫ (& + #8747;)
