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!

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.

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

Share links to great relevant problems.

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.*

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!

Good Car, Bad Car

Log in to reply

The car in the image is definitely a bad car. But the problem is good. ;) Thanks!

Log in to reply

Filling up Spheres: This is an old problem, and is not just about solids of revolution. I hope this can do, though. :)

I Request @Sandeep Bhardwaj sir to add these problems too to his previous comment

Log in to reply

Just awesome!

Log in to reply

sir i am not able to see points a problem corresponds to only the level of problem is visible . can you help?

Log in to reply

@Prakhar Bindal

Brilliant doesn't display the points of a problem anymore. Only the level is displayed. So, enjoy with the level itself. ;)Log in to reply

Here is a problem on Similarity

Log in to reply

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:

Before

After

Log in to reply

@Andrew Ellinor

I am redrawing it right away Sir. :D
