Problem Writing Party: March 28th - April 10th

Hello Brilliant!

Once more, Problem Writing Party number 5 was a record breaking success: this time we made nine new quizzes! Here are the quizzes that you all helped create:

New Brilliant Challenge Quizzes
Simple Harmonic Motion: Level 2-3
Simple Harmonic Motion: Level 4-5
Functions: Level 3
Functions: Level 4
Functions: Level 5
2D Coordinate Geometry: Level 3
2D Coordinate Geometry: Level 4
2D Coordinate Geometry: Level 5
Capacitors and Transformers: Level 2-3

We're going to show off all the hard work these members of the community put in over the last week. Continue submitting your fantastic problems as we kick off our sixth Problem Writing Party!

How it Works

The party starts right now (March 28th, 2016) and will last for the next two weeks. Throughout the two weeks, we will be focusing on writing awesome problems for the topics listed in quizzes that need your help on the publish page.

To join, submit as many problems as you want to these listed topics. At the end of the party, Brilliant staff will be picking the best 5-10 problems for each topic. These problems will then be immortalized and formed into a challenge quiz. If we pick your problem, then you can brag to your friends because it will be displayed on Brilliant forever! Your problem has a better chance of being selected if you include a graphic (when appropriate) and a solution.

Use this note to

  1. Ask questions about the party or brainstorming ideas from Brilliant staff.

  2. Share links to great relevant problems.

  3. Bounce your ideas off each other to help formulate the best problem you can.

To be selected, problems you submit should be fun and challenging to a student in levels 1-3 for the given topic.

-------->This Party's Topic Listing<--------

The topics of problem submission for this party can be found by navigating over to the Brilliant publish page and checking under the quizzes that need your help section. Just click the contribute button next to the topic you want to make a submission to.

Happy writing and keep the party alive!

Great problem Soumava! I recommend redrawing your graphic though. The numbers are a little too small to read and they'll be even smaller if added to a quiz. Moreover, be smart about your canvas size. Make sure your graphic fills up the entire canvas instead of leaving white space around the edges. See the difference below:
