Eevblog forum equation editor?

[jesuscf]

Maybe this has been asked before, if that is the case could you please pass the link?  (Googling "eevblog equation" returns thousands of unrelated results!) Otherwise, is there a way of posting equations in the forum?  Something like

Code: [Select]

[tex]y = a x^2 + bx + c[/tex]

[Andy Watson]

Surround the equation with \ $  (without the space)  \$y = a x^2 + bx + c\$
Use $ $ without the space to format the equations in their own space.  $$y = a x^2 + bx + c$$

[Cyberdragon]

But how would you do advanced symbols like integrals, limited summations, exc?

[Andy Watson]

It's essentially Tex/LaTeX code.  \$\int_0^2 x^2 dx\$

Surround the equation with \ $  (without the space)  \$y = a x^2 + bx + c\$

Preview doesn't show the result for me.  Let me try posting...

\$y = a x^2 + bx + c\$
\$\int_0^2 x^2 dx\$

Edit: it works!  Thanks Andy Watson!

This can help with getting a preview of the result before you post:

BTW, for display equations surround them with $$ rather than \$.

I like the standard equation editor in Word.
Is there any way to copy an equation from Word into the forum?

Yes--if you are using Office 365.

1. Enter the equation in Word.
2. Change the equation to LateX using the Conversions area in the Equation Tools--Design tab on the ribbon.
(3. Change the equation display format to Linear.)
4. Copy the LaTeX equation markup from Word into the forum.

Note: Step 3 may not be necessary depending on your equation editor settings.

Example:

I write this equation in Word: 1+1/(2+1/(2+1/(2+⋯)))=√2
I check that it displays nicely.
I convert it to LaTeX.
I copy it to the clipboard.
I paste it here.
It looks like this:
$$1+\frac{1}{2+\frac{1}{2+\frac{1}{2+\ldots}}}=\sqrt2$$

There is a short tutorial at https://math.meta.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference

When I read through this thread, at first, I couldn't figure out what everyone was talking about.  Then I saw a reference to mathjax and the light went on.  My security settings routinely block almost all web sites.  These equations only display properly when I allow mathjax.org and cloudflare.com.  Anyone who has trouble seeing the equations should check their security software.  In my case, it was the Noscript plugin for Firefox.
