Content location → Definite integralsEvidenceEditorial scope: f is Riemann integrable on the finite interval [a,b], with a<b; continuity is sufficient. Sample points belong to their subintervals and the largest subinterval width tends to zero. For the displayed equal partition, n→∞ ensures this. A nonnegative f gives ordinary area; a sign-changing f gives net signed area.
