Hello, I'm --WikiUser1234945--. An edit you recently made to Proofs of trigonometric identities seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. --WikiUser1234945-- (talk) 18:36, 8 September 2023 (UTC)
