- the representation, usually in symbolic form, of the difference in values of a primitive of a given function evaluated at two designated points.
- maths
- the evaluation of the indefinite integral between two limits, representing the area between the given function and the x- axis between these two values of x
- the expression for that function, ʃ b a f (x) dx, where f (x) is the given function and x = a and x = b are the limits of integration. Where F (x) = ʃ f (x) dx, the indefinite integral, ʃ b a f (x) dx = F (b) –F (a)
