Lijst van integralen van hyperbolische functies

Dit artikel bevat een lijst van integralen van hyperbolische functies. Integralen zijn het onderwerp van studie van de integraalrekening. De hyperbolische functies zijn analogieën van goniometrische functies. Er wordt van alle integralen de primitieve functie gegeven, maar de integratieconstante is in de uitkomst steeds weggelaten.
