The nominator has neither edited the article nor discussed the nomination on the talk page. In fact, the nominator appears to have made only one edit to a computer science article, no edits to any mathematics article, and no other edits to articles of a technical nature before this nomination. The lead does not adequately summarize the article. The first section, "Overview", is an unreadable mass of boldfaced synonyms and citation overkill. The next section, "History and applications", has multiple unsourced paragraphs, and appears to be a collection of random facts thrown together in a random order rather than having any logical structure. The "Definitions" section has no text at all, as do several subsequent sections. The "Circular rotations" section has no references at all. The references section includes an excessively long quotation (although not a copyvio as the source is public domain by now). Many of the references are to the dubiously-reliable MathWorld. Several references are to publications with unknown titles that the person using the reference obviously has not read, because they go on to say "according to [someone else], this reference says [something vague about the subject]". The Stávek reference is to an unreliable predatory journal, as is the Stávek entry in "further reading". There is a year-old and still-valid "citation needed" tag on the supposed and unlikely Indian etymology of the Latin word for an arrow. If one wishes to find applications of this function, they are scattered in multiple sections, none of them with section headings identifying them as applications. Given that the versin is such a trivial variation of the cos, there is no indication why the article on it needs to go into such intricate detail about many many other trigonometric functions that are also trivial variations on cos; this is supposed to be an article on versin, not a catalog of all other trigonometric functions. This is very far in many ways from being a Good Article; I think it should be an immediate fail, per WP:GAFAIL. —David Eppstein (talk) 05:45, 24 April 2020 (UTC)
