Definition: Indefinite Integral The indefinite integral of r with respect to t is the set of all antiderivatives of r, denoted by . If R is any antiderivative of r, then Quick Example – Evaluate:
Definition: Definite Integral If the components of r(t) = f(t)i + g(t)j are integrable on [a, b], then so is r, and the definite integral of r from a to b is Quick Example – Evaluate:
