Calculate definite integrals of continuous functions using the theorem of integral calculus. After examining the concept of the primitive of a function, it's time to discuss the definite integral, which, unlike the indefinite integral, returns (if it exists) a real number. We start by determining the area of ​​a plane surface of any shape, and naturally we arrive at the Riemann integral of a continuous function on an interval. As you'll see, the study of a definite integral always leads to the search for a primitive, and using the fundamental theorem of integral calculus (whose proof I omit), we find the desired real number.
