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]
$$y = a x^2 + bx + c$$

Bart: Isn't that the wrong way?
Homer: Yeah, but faster!

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. $$y = a x^2 + bx + c$$ « Last Edit: January 20, 2019, 06:49:01 pm by Andy Watson » The following users thanked this post: jesuscf, apis #### Cyberdragon ##### Re: Eevblog forum equation editor? « Reply #2 on: January 20, 2019, 06:37:51 pm » But how would you do advanced symbols like integrals, limited summations, exc? *BZZZZZZAAAAAP* Voltamort strikes again!

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 \. « Last Edit: January 20, 2019, 06:54:50 pm by IanB » I'm not an EE--what am I doing here?

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

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.
