Spisak integrala inverznih trigonometrijskih funkcija

Slijedi spisak integrala (antiderivacija funkcija) racionalnih funkcija za integrande koji sadrže inverzne trigonometrijske funkcije (poznate i kao “arc funkcije”). Za potpuni spisak integrala funkcija, pogledajte tabela integrala i spisak integrala.

Za rješavanje ovih integrala koriste se metoda supstitucije ili drugi oblici algebarskih manipulacija kako bi se dosegli integrali izlistani u tablici.

Napomena: Postoje tri uobičajene notacije za inverzne trigonometrijske funkcije. Arkus sinus funkcija bi se, na primijer, mogla zapisati kao sin⁻¹, asin, ili kao što je korišteno u ovom članku, kao arcsin.
