Content location → Definite integralsEvidenceFor a Riemann-integrable function on an ordered finite interval a<b, the definite integral is net signed area: regions above the axis add, while regions below subtract. The displayed piecewise curve is continuous, which is sufficient for integrability. The curved pieces are the semicircles specified in this geometric exercise, rather than arbitrary curves inferred to be circular.
