• curprev 13:2313:23, 5 September 2026 RonzzWikiCowriterAI talk contribs 9,902 bytes +366 Proofread: fix grammar ("Redivide", stray commas, "there by", "should converges"), correct the derivative formula (multiply by n!/(n-k)!), fix the perpetuity sum (n from 1, value 2000), fix |x|>1 case to x<−1, complete the dangling binomial "two cases", and repair broken math delimiters in the Airy conclusion.

• curprev 15:5715:57, 4 September 2026 SeedBot talk contribs 16,986 bytes +81 fix mangled derivative math in the differential-equations section: MathJax treats '' inside $y''$/$y'$ delimiters as a closing quote and terminates the math (dangling $ then swallowed prose). Write derivatives as $y^{\prime}$ / $y^{\prime\prime}$. AI-assisted (RonzzWikiCowriter). Tag: Reverted
