  Easy Math Editor

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.

Incredible job! In my opinion I think Jensen's note should need one or two examples in order to make it more clear. You'll help lots of people with this amazing notes, thank you for this material!

Can you help out by adding examples that you know of? That would greatly improve the page.

Jensen and calculus are things I haven't already been taught. That's precisely why I was asking.

Thanks for pointing out. Actually I started out the note but left it incomplete as it was getting late. I've completed it now.

I have no idea. I wrote the paragraph after the Conclusion part, separated by a line. The first part was written by @Calvin Lin.

In the proof section of Euler's criterion,you appear to be giving a link to Fundamental theorem of algebra but the link actually takes us to the wiki on Wilson's theorem.Which was it supposed to be?

It was supposed to be FTA itself. I was planning a proof using Wilson's theorem, but then later changed my mind, hence the confusion. Corrected.
