We find this identity, that looks like an exercise in Calculus 1, surprising, and beautiful. We hope that you would too.

shikiteibakin: 符号のミスを Greg Egan に指摘されて訂正したというこの論文(?) https://t.co/jHznaREcLF 4. This version corrects a sign typo pointed out by Greg Egan. 5. Watch Greg Egan’s beautiful animation in https://t.co/KUVJoICVkF アニメーションはリンク切れ. 残念.

gregeganSF: Thanks to @sigfpe, a surprising equality between definite integrals, proved by Zeilberger et al: https://t.co/ggsr1xQ3Um The proof there is by induction for non-negative integers n, but the identity seems to hold for all n>0.
