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.

Thank you!

Contributing to the Brilliant wiki is one of my favorite pastimes. I'll try my best to keep contributing to the wiki and make Brilliant a better place.

Mursalin Habib Thanks for the wiki - The extremal principle

Can you make it more long , its very interesting to read, taken a print out too.

- 4 years, 9 months ago

Can you be more specific about what you want to see in that wiki? You can comment on this note to let the community know what improvements you want to see in wikis.

@megh choksi How do you take printouts of the Latex

- 4 years, 8 months ago

there is an option in the browser from where you can directly print it

Daniel Liu Thanks for the Reverse Rearrangement Inequality Wiki!

Are there any other interesting problems that use this approach?

Staff - 4 years, 9 months ago

It serves as a great introduction to those who are learning about Induction! Do you think it would be good to standardize the proof format, stating "Base case" and "Induction Hypothesis"?

Pranshu Gaba Jubayer Nirjhor Krishna Ar Thanks for the Factors Wiki!

You did a great job explaining how to find the number of factors and also the sum of factors!

@josh silverman Thanks for the Fermi Problems wiki! The examples were well-developed and interesting to read and try out. Great job!

- 4 years, 8 months ago

I did enjoy that read too! Fermi problems are not well appreciated in schools where absolute answers are needed. However, they form an integral aspect of working life, where you have to make reliable guess-timations.

@Prasun Biswas Thanks for the Newton Identities wiki. I've cleaned it up and improved on the Latex presentation.

It could still use a proof of the theorem. Any takers?

Staff - 4 years, 8 months ago

@Prasun Biswas We just shared the Newton's Identity wiki on our Facebook page, and people really love it!!

Staff - 4 years, 8 months ago

@Jubayer Nirjhor Thanks for your wiki on De Moivre's Theorem

Especially, I liked the "The nth Roots of Unity"

- 4 years, 8 months ago

@Archit Boobna @Christopher Boo I got around to adding your Fibonacci Series to the Fibonacci numbers skill map. Thanks!!

Staff - 4 years, 8 months ago

@Rohan Nuckchady Thanks for Quadratic Diophantine Equations - Solve by Factoring. I've marked it for cleanup as you didn't follow the formatting guidelines exactly, but we appreciate the examples.

Staff - 4 years, 8 months ago

@Kishlaya Jaiswal thanks for your post on Generalizing the Circular Functions! Also, great work on Vandermonde's Identity.

Staff - 4 years, 8 months ago

@Sudeep Salgia @Raj Magesh Thanks for the Derivative by first principle wiki. I liked the additional problems which you listed, and they are all great examples of its applications.

@Calvin Lin @Arron Kau : Thanks for the 'Method of Differences' wiki. I'll be using it to bash sequence problems in tomorrow's math test.

Staff - 4 years, 7 months ago

@Patrick Corn Thanks for the awesome collection of wikis you've written. They're very clearly written and explain the concepts very well.

- 3 years, 7 months ago

@Josh Silverman Thanks for the Lagrangian formulation of mechanics wiki! I just came across it and it was very well-written and informative.
