Hello, I'm SHB2000. I noticed that you added or changed content in an article, History of trigonometry‎, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. SHB2000 (talk) 07:27, 7 October 2022 (UTC)[reply]

If this is a shared IP address, and you did not make the edits referred to above, consider creating an account for yourself or logging in with an existing account so that you can avoid further irrelevant notices.

Please do not add or significantly change content without citing verifiable and reliable sources, as you did with this edit to History of trigonometry. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. Adakiko (talk) 09:29, 7 October 2022 (UTC)[reply]

This is the discussion page for an IP user, identified by the user's IP address. Many IP addresses change periodically, and are often shared by several users. If you are an IP user, you may create an account or log in to avoid future confusion with other IP users. Registering also hides your IP address.
