content: 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 likeCode:y = a x^2 + bx + c

content: 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. $$y = a x^2 + bx + c$$

content: Quote from: TimFox on January 21, 2019, 11:33:46 pmYes--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+⋯)))=√2I check that it displays nicely.I convert it to LaTeX.I copy it to the clipboard.I paste it here.It looks like this:$$1+\frac{1}{2+\frac{1}{2+\frac{1}{2+\ldots}}}=\sqrt2$$

content: 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.Ed
