In calculus and mathematical analysis the limits of integration of the integral

of a Riemann integrable function f defined on a closed and bounded [interval] are the real numbers a and b.

Improper integrals[edit]

Limits of integration can also be defined for improper integrals, with the limits of integration of both

and

again being a and b. For an improper integral

or

the limits of integration are a and ∞, or −∞ and b, respectively.
