    Antiderivatives Help

    Introduction to Antiderivatives Many processes, both in mathematics and in nature, involve addition. You are familiar with the discrete process of addition, in which you add finitely many numbers to obtain a sum or aggregate. But there are ...

    Area Under a Curve Help

    Introduction to Area Under a Curve Consider the curve shown in Fig. 4.1. The curve is the graph of y = f ( x ). We set for ourselves the task of calculating the area A that is (i) under the curve, (ii) above ...

    Signed Area Help

    Introduction to Signed Area Without saying so explicitly, we have implicitly assumed in our discussion of area in the last section that our function f is positive, that is its graph lies about the x-axis. But of course many functions do not share ...

    The Area Between Two Curves Help

    Introduction to The Area Between Two Curves Frequently it is useful to find the area between two curves. See Fig. 4.17. Following the model that we have set up earlier, we first note that the intersected region has left endpoint at x = a ...

    The Indefinite Integral Help

    Introduction to The Indefinite Integral In practice, it is useful to have a compact notation for the antiderivative. What we do, instead of saying that “the antiderivative of f (x) is F(x) + C ,” is to ...

    The Fundamental Theorem of Calculus Help

    Introduction to The Fundamental Theorem of Calculus The most important idea in all of calculus is that it is possible to calculate an integral without calculating Riemann sums and passing to the limit. This is the Fundamental Theorem of Calculus, due to Leibniz ...

    Areas Under Curves Study Guide

    Areas Under Curves Around the same time that so many great mathematicians devoted themselves to figuring out the slopes of tangent lines, other mathematicians were working on an entirely different problem. They wanted to be able to figure out the area underneath ...

    The Fundamental Theorem of Calculus Study Guide

    The Fundamental Theorem of Calculus Here comes the resounding climax of calculus. It would be best to read this lesson with some bombastic orchestral music like that of Wagner or Orff. This, however, is not necessary. The initial question here is innocent enough: ...
