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
b.
the expression for that function, ∫baf(x)dx, where f(x) is the given function and x = a and x = b are the limits of integration. Where F(x) = ∫f(x)dx, the indefinite integral, ∫baf(x)dx = F(b)–F(a)
definite integral in American English
Ancient Mathematics
an integral in which the range of integration is specified: its value equals the area on a graph bounded by a curve, the x-axis, and two given ordinates
