A definite integralis an integral with limits. The limitsare represented as small numbers at the top and bottom of the integral. We integrate in exactly the same way, except we can leave out the constant of integration +c+c. Then, we get our final answer by substituting the limits into our integrated form, and taking the value for the lower limitaway from the value for the upper limit.

Definite integrals are useful because they represent the area under the graph.
