Definite integrals

concept
  • Explanation → Definite integrals
    EvidenceConnection evidence is not yet available in this language.
  • Explanation → Definite integrals
    EvidenceFor a<b and integrable, nonnegative f on [a,b], the integral equals ordinary area beneath the graph. More generally an integral records signed accumulation; ordinary area for sign-changing f uses |f|, when integrable.
