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.

Thanks! These are really helpful and interesting :)

Indeed. More wiki = more awesome.

Just a quick question: Is the Calculus development section coming up? Cause I'm chipping in for Multivariable Calculus - the course I'm taking right now.

Just curious.

You can "Add Wiki" if you want to make a Wiki page for a skill that is not listed yet. If the page is suitable, we will add it to the current map.

The Calculus section is almost fully developed for a typical high school syllabus. Over time, I will get around to adding extensions to it. Currently, I am fleshing out the Geometry and Combinatorics sections, which are much further behind.

Where can I put into the fact that "A Quadratic Equation cannot have more than 2 roots." And What Exactly does one need in Quadratics-Factoring-Medium. I am just thinking for writing up that.also..many, but the matter is I am using some proofs to prove many others so should I first make sure that those proofs exist and then go forward in writing up the the proof that I want to add to Wiki.

The first fact can be placed in Quadratic Equations - Factoring.

You can also create a new skill of "Fundamental Theorem of Algebra" and place it there, and add more details about the general $n$ degree polynomial.

Proofs of statements are certainly welcome, and will help provide more context to those who are interested. If you do not see a suitable place to add the proof, please use the "Add Wiki" page. Thanks!

Indeed, those are very nice articles. What a tour of force from the brilliant users here!

Here are some calculus problems that I posted. ☜(ˆ▿ˆc)

It is a good Facility provided by brilliant nice!!!!!!!!!!!!!!!!!!

Yogesh Ghadge - 6 years, 7 months ago

may i add a page on MAT(reasoning)

Certainly! Go to "post something" and select Wiki.
