# The second fundamental theorem of calculus

## Second Fundamental Theorem of Calculus referred to as the second fundamental theorem of calculus or the The second part is somewhat stronger than the corollary.

In this section, we strive to understand the ideas generated by the following important questions:. In Section 4. For the former, see Preview Activity 5. For the latter, we can easily evaluate exactly integrals such as. From a second perspective, the First FTC provides a way to find the exact value of a definite integral, and hence a certain net-signed area exactly, by finding an antiderivative of the integrand and evaluating its total change over the interval.

How do the First and Second Fundamental Theorems of Calculus enable us to formally see how differentiation and integration are almost inverse processes? For the latter, we can easily evaluate exactly integrals such as. Thus, the First FTC can used in two ways. In addition, the First FTC provides a way to find the exact value of a definite integral, and hence a certain net signed area exactly, by finding an antiderivative of the integrand and evaluating its total change over the interval. The value of a definite integral may have additional meaning depending on context: as the change in position when the integrand is a velocity function, the total amount of pollutant leaked from a tank when the integrand is the rate at which pollution is leaking, or other total changes if the integrand is a rate function. Doing so, we observe that. The Second FTC provides us with a way to construct an antiderivative of any continuous function.

The fundamental theorem of calculus is a theorem that links the concept of differentiating a function with the concept of integrating a function. The first part of the theorem, sometimes called the first fundamental theorem of calculus , states that one of the antiderivatives also called indefinite integral , say F , of some function f may be obtained as the integral of f with a variable bound of integration. This implies the existence of antiderivatives for continuous functions. Conversely, the second part of the theorem, sometimes called the second fundamental theorem of calculus , states that the integral of a function f over some interval can be computed by using any one, say F , of its infinitely many antiderivatives. This part of the theorem has key practical applications, because explicitly finding the antiderivative of a function by symbolic integration avoids numerical integration to compute integrals.

Fundamental Theorems of Calculus. Warning, the name changecoords has been redefined. This is the lesson in which the connection between definite and indefinite integrals is exposed. At this point Indefinite Integrals , antiderivatives, are obtained by reversing the differentiation process. There are two Fundamental Theorems of Calculus.
