An integral expressed as the difference between the values of the integral at specified upper and lower limits of the independent variable.

i.e.,

The definite integral of *f(x)* between *a *and *b* represents the area under the curve *y = f(x)*, above the x-axis to the right of the line *x = a*, and to the left of the line *x = b*. The definite integral of *f(x)* = F(b)-F(a) where F is an anti-derivative function for *f(x)*.
