Weekend Wiki Party 9 - Empty Pages

This week, we're trying something a little different with the Weekend Wiki Party, and there should be something here for everyone. Below, you'll find the most visted pages in each topic on Brilliant that currently have no content.

These pages are about things that people on Brilliant want to know about, but there's currently nothing on our wiki to help them. Can you help them out by adding to these pages?

Leave a comment if you make an edit, and thanks for helping make Brilliant the best place in the world to learn math and science!

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.

@Calvin Lin Sir, I contributed to the "Absolute Value" Wiki.I added examples to each section , improved the definition and added some properties to the notes of absolute value.Hope you like it :)

Thanks! That page is beginning to look better :)

Calvin Lin Staff - 6 years, 1 month ago

Is it okay, if I help with these pages after JEE, that is, next week? I am saving this note so that I can remember to do so.

Vishwak Srinivasan - 6 years, 1 month ago

Certainly! Help at any point in time will be welcome.

All the best with JEE!

Calvin Lin Staff - 6 years, 1 month ago

Thank you sir!

Edited out/Cleaned up $\text{Perfect Numbers } \ddot\smile$

Pranjal Jain - 6 years ago

Oh yay! That page looks much better than it did the day before.

It could benefit from adding some proofs, or combining the list of properties which are mostly "it has the form $2^{n-1} ( 2^n - 1 )$ .

Sir, i've contributed to the graphs of inverse trigo. can u check it??

A stopwatch has a least count of 0.1 seconds it does 20 oscillations in 25 seconds find error in time period

abhishek singh - 6 years ago

0.125secs?

Ayanlaja Adebola - 6 years ago

In response to ayanlaja answer, please can you tell how the answer came

abhishek singh - 6 years ago

@Abhishek Singh – Am i corect or wrong?

Ayanlaja Adebola - 6 years ago

@Abhishek Singh – I think.....Period(T)=Time Taken/Number of oscilations.......T=25/20.....T=1.25 secs.....Since the stopwatch moves @least 0.1secs which is its reading accuracy....Error=1.25*0.1=0.125secs
