The definite integral of a function f(x) in x between limits a and b is basically the area between f(x), x=a, x=b and the coordinate axes.

If the indefinite integral of f(x) is F(x) then definite integral is F(b) – F(a).

Difference between the Definite and Indefinite Integral

Definite Integral has the upper and the lower limits which give the area under the curve of the given function as mentioned from the lower to the upper limit. It does not have the constant of integration.

Indefinite integral does not have the upper and the lower limit, and it gives a general solution to the differential equations. It has a constant of integration which gives the general form of integration.
