Proofathon Trigonometry and Complex Numbers

Hello Proofathoners and Brilliantitians alike!

The Trigonometry and Complex Numbers contest has started. Check it out at proofathon.org. We have a great set of problems in store, and my personal favorite is Problem 8. These problems were made by fellow Brilliantitians like Sreejato Bhattacharya, Logan Dymond, Nicolae Sapoval, and Pi Han Goh.

Proofathon

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.

@Jatin Yadav Fear not! It was an error on our part: (z)>0\Im(z)>0 rather than (z)>0\Re(z)>0.
