== Welcome to Wikipedia ==

Hi M. Safin Alam, and welcome to Wikipedia.

I reverted your change to [[Spherical trigonometry]], because I think it was a bit misplaced in the lead section. In general, anything in the lead section needs to be either introductory context or a summary of claims made in the body of the article; a discussion of the history of a topic should go into a "History" section somewhere in the page (for this article, probably toward the bottom), since it's not really the most important introductory thing for most article readers to see.

But please do feel free to re-add similar historical material to the pages or sections where it would be a bit more topical. I'd love to e.g. see some expansion of [[Menelaus's theorem]] predominantly focusing on the spherical case, which was historically more important and influential than the planar case, and some comparison (not sure the right venue, perhaps a section of [[Spherical trigonometry]], but definitely not the lead section) comparing spherical trigonometry focused on quadrilaterals vs. focused on triangles. There should probably be dedicated sections of at least the [[Trigonometry]] and [[History of trigonometry]] articles discussing the way the introduction of logarithms changed calculations, and perhaps an entire article dedicated to that topic. Etc.

So I don't want to chase you away, and hopefully my revert doesn't seem too much like a rejection. Let me know if there's anything in particular you want to collaborate on: I've been disappointed in the state of these articles for a long time, and I have a strong interest in spherical geometry and mathematical history. (e.g. I wrote [[Lexell's theorem]] thinking it would have a relatively small and contained scope, hoping that it would inspire me to make a bunch more similar diagrams of other spherical geometry topics, but then I stalled and never got back to it.) –[[user:jacobolus|jacobolus]] [[user_talk:jacobolus|(t)]] 08:16, 19 April 2026 (UTC)
