# Wiki Weekend Party 19 - Pages people chose

It's the time of the week again, where the Brilliant community collaborates on parts of the wiki, and help improve them so that others can get a good understanding of the concept, and see relevant, interesting examples.

A Brilliant wiki has a brief overview of a topic, followed by tons of examples and applications. It should also have the following attributes:

• Engaging perspective The topic is introduced in a way that explains why a person should be interested.
• Illuminating examples Key concepts are illustrated through examples that build intuition and quickly convey a practical knowledge of how to solve common problems.
• Visual appeal The page is well-organized, easy to read, and integrates helpful images, GIFs, and videos.
• Interactivity The page contains quizzes and problems for the reader to try, to see if they understand the concepts and techniques in the wiki.

Brilliant wiki pages are written at the reading and comprehension level of an advanced high school student.

This week, I've selected from a list of pages that people have indicated they are interested in working on. As such, we will draw from a wide range of topics. The list is:

• Sine and Cosine Graphs
• Cryptogram
• Arithemtic-Geometric Progression
• Periodic motion
• Power input to a system
• Inductive Effect, Electromeric Effect, Resonance, and Hyperconjugation
• Ionic Compounds

You can see the updated list here, check out who else is working on it and see the feedback from the community on pages that you've written.

If you are interested in helping out, come chat with us.

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.
