Hello Brilliant community,

There are some chapters which don't have quizzes for the community to work on and they need your help. You can help Brilliant by contributing some good problems in those chapters. The list of those chapters can be found when you click on "Publish" button as you can see below.

After clicking on the "Publish" button you will see list of the chapters that need your help, which looks like:

You are free to post all level problems. And you can see your good enough problems in the challenge quizzes of the community. I will also contribute the problems to get the Brilliant with more amazing problems. And I'm looking forward for your contributions too.

Thanks a lot!

Can you teach me how to post a link in Latex. I'm having trouble with it. Thank you. ;)

To post the link in Latex, do the following:

\[\text{[Name of the problem](link) }\]

And it will be displayed as Name of the problem.

Thanks :) umm I have question. Is there any place where I can see the complete formula/equations list? Or a link where I can improve my skills in using \(Latex\) kind of fonts.

I'll look forward for any tutorials or helpful link here. Thank you very much :)

@Julius Adrian

You can get a lot of Latex guides from Daniel's note: Beginner LaTex Guide. And if you're looking for the complete guide, then refer to the wikipedia page: LaTex/Mathematics.

Hope it will be helpful. Thanks!

Here is an extensive guide to using \(\LaTeX\). Except the points 1 and 2, all the other points are universally applicable wherever you use \(\LaTeX\)/MathJax.

The alternative to point 1 in this site is to hover your mouse cursor over the equations to see the raw \(\LaTeX\) code or use the "Toggle \(\LaTeX\)" option from the pop-down menu in the top right area (click on the small circled profile pic area).

The alternative to point 2 in this site is use \(\backslash(\ldots\backslash)\) instead of \(\$\ldots\$\) and to use \(\backslash[\ldots\backslash]\) instead of \(\$\$\ldots\$\$\).

The answer posts on that post further elaborate on how to make tables, matrices, etc.
