About

I love solving and making recreational math puzzles. My specialties at university were Computer Science and Mathematics.

If you love proving trigonometric identities or if you are preparing for a trigonometry test, check out my TRIGONOMETRIC IDENTITIES WORKBOOK at the Internet Archive. It contains 21 examples of proofs of trigonometric identities and several identities for you to prove.
