Problem Contribution in Chapters

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!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I've posted a problem in Percentages chapter. You would love it: What is your LCM?

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

Worranat Pakornrat - 5 years, 5 months ago

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.

@Sandeep Bhardwaj – Thanks! I added the new question in the Quadratic Discriminant chapter: Perfect Squares Only

Worranat Pakornrat - 5 years, 5 months ago

@Worranat Pakornrat – Great! Nice problem, thanks!

@Sandeep Bhardwaj – @Sandeep Bhardwaj , I want to contribute in quadratic discriminant , should I share link of problem here ?

@A Former Brilliant Member – Not compulsory, but you can if you wish.

Sandeep Bhardwaj - 5 years, 5 months ago

For triangles , is this problem suitable ?@Sandeep Bhardwaj

A Former Brilliant Member - 5 years, 5 months ago

I made a simple problem in percentages : 2016%

Thanks Julius! Nice problem. :)

Sandeep Bhardwaj - 5 years, 5 months ago

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 – @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!

Sandeep Bhardwaj - 5 years, 5 months ago

@Julius Adrian – 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.

I have come up with a new question in Volume 3D chapter: 5 Pyramids in 1 Cube

Enjoy! ;)

Worranat Pakornrat - 5 years, 5 months ago

I've just posted a new problem on the Triangle Chapter: Lucky Star Number 7 .

Hope you'll enjoy its beauty. ;)

Worranat Pakornrat - 5 years, 5 months ago

Wow! What a nice problem! Thanks :)

Sandeep Bhardwaj - 5 years, 5 months ago

There you go! That's my problem for volumes. Filling The Tank
