There is a reason it is called the Fundamental Theorem of Calculus. Second, it is worth commenting on some of the key implications of this theorem. So the function returns a number (the value of the definite integral) for each value of x. The key here is to notice that for any particular value of x, the definite integral is a number. At first glance, this is confusing, because we have said several times that a definite integral is a number, and here it looks like it’s a function. Note that we have defined a function, as the definite integral of another function, from the point a to the point x. Its very name indicates how central this theorem is to the entire development of calculus.īefore we get to this crucial theorem, however, let’s examine another important theorem, the Mean Value Theorem for Integrals, which we use to prove the Fundamental Theorem of Calculus.īefore we delve into the proof, a couple of subtleties are worth mentioning here. This relationship was discovered and explored by both Sir Isaac Newton and Gottfried Wilhelm Leibniz (among others) during the late 1600s and early 1700s, and it is codified in what we now call the Fundamental Theorem of Calculus, which has two parts that we examine in this section. These new techniques rely on the relationship between differentiation and integration. In this section we look at some more powerful and useful techniques for evaluating definite integrals. Unfortunately, so far, the only tools we have available to calculate the value of a definite integral are geometric area formulas and limits of Riemann sums, and both approaches are extremely cumbersome. In the previous two sections, we looked at the definite integral and its relationship to the area under the curve of a function. Explain the relationship between differentiation and integration. ![]() Use the Fundamental Theorem of Calculus, Part 2, to evaluate definite integrals.State the meaning of the Fundamental Theorem of Calculus, Part 2.Review the notions of an Antiderivative and an Indefinite Integral, the Table of Antiderivatives, and the Properties of Indefinite Integrals.Use the Fundamental Theorem of Calculus, Part 1, to evaluate derivatives of integrals.State the meaning of the Fundamental Theorem of Calculus, Part 1.Describe the meaning of the Mean Value Theorem for Integrals.
