Hello, I'm Anita5192. I noticed that you recently removed content from Trigonometric functions without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. — Anita5192 (talk) 17:06, 7 May 2021 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did at Timeline of programming languages. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. Dl2000 (talk) 14:07, 8 May 2021 (UTC)
