Seeing actual \( \LaTeX\)

We have provided a simple way to view the Latex code which generates all the wonderful math equations that you see.

If you hover over an equation (place your mouse over it for a second), it appears in a box:

You can test this feature with the following line of LaTeX:

\[ e^{i \pi } + 1 = 0, \quad i \, \heartsuit \text{ Brilliant!} \]


Note: This does not apply to images of LaTeX that members uploaded to problems or solutions.

Update: The following functionality has been removed (explanation):

Additionally, if you click on the menu in the top right corner, and select "Toggle LaTeX", we will then display the latex code, instead of the actual equations. Selecting it again would display the equations.

This allows you to easily read see all of the latex on the page. Furthermore, you can select the text, copy, and paste it into your comment (and then edit it). This way, you can easily reference specific equations.

Refer to this video for an example.

"Toggle LaTeX" isn't an option anymore. Was this intentional?

Log in to reply

Hi @Blan Morrison – yes, it is intentional.

Silas Hundt Staff - 3 months, 1 week ago

I don’t mean to be intrusive, but would you mind explaining why that decision was made?

Blan Morrison - 3 months, 1 week ago

Log in to reply

@Blan Morrison Not intrusive at all. We removed it for three reasons:

  1. There are many great places on the internet to learn how to write LaTeX, and we're never going to do a good job contributing in this area.
  2. It was a somewhat troublesome feature to maintain.
  3. It was actively confusing to some users – we received plenty of questions about it from users.

Note that you can still see the LaTeX that was used to generate LaTeX on the screen by hovering over it.

No support in the Brilliant app yet, sorry :/ You can work around this issue by opening the page in the mobile browser and using the Toggle LaTeX menu from there.

Can you make some keyboard shortcut to toggle latex?

Abhishek Sharma - 3 years, 9 months ago

Unfortunately no, not at this moment. We will keep that in mind if a lot of people start using "Toggle Latex", and want a shortcut.

I can't find the "Toggle LaTeX" command anymore. Is it still available? It's a real help to learn LaTeX!

Gabriel Chacón - 3 months ago

Log in to reply

Ok. Don't bother to answer. I just read the post by Blan Morrison and the replies. The toggle LaTeX command was really helpful to me. I am a bit disappointed at the decision to remove it, though I understand you have your reasons.

Gabriel Chacón - 3 months ago

Log in to reply

Yay, finally a feature like this! This will definitely help a lot of LaTeX newbies out there :D

EDIT: things like these still don't work yet apparently: \[\left\{\begin{array}{l}\text{Equation 1}\\\text{Equation 2}\end{array}\right.\]

EDIT2: Hm, the "toggle latex" option doesn't work. It toggles everything on the main feed, but once you click on a problem, it just shows the regular latex.

Daniel Liu - 4 years, 1 month ago

Log in to reply

Regarding the first edit: it doesn't work on comments that you just typed in. Once you refresh the page, the latex will be displayed.

This is a screenshot of what I get on your comment:

Calvin Lin Staff - 4 years, 1 month ago

Currently, you need to open the problem in it's own window for Toggle LaTeX to work (it doesn't work in modals).

Instead of using \( \backslash[ \quad \backslash] \), use \( \backslash( \quad \backslash) \) around your Latex code instead. The former forces the equation into a newline (as you realized), but the latter allows things to continue on in the paragraph.

I've edited your comment so you can take a look at it.
