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.
