6.4: Arc Length of a Curve and Surface Area

AP Calculus BC. Search this site. General Resources. Summer Assignments. Tuesday, July 10th.

Many solid objects, especially those made on a lathe , have a circular cross-section and curved sides. On this page, we see how to find the volume of such objects using integration. NOTE: On this page we use the disk method and washer method where we cut the shape into circular slices only, and meet the Shell Method next. When we rotate such a shape around an axis, and take slices, the result is a washer shape with a round hole in the middle. Find the volume of the material needed to make the cup. This is consistent with what we see in the graph above.

In this section, we use definite integrals to find the arc length of a curve. We can think of arc length as the distance you would travel if you were walking along the path of the curve. Many real-world applications involve arc length. If a rocket is launched along a parabolic path, we might want to know how far the rocket travels. Or, if a curve on a map represents a road, we might want to know how far we have to drive to reach our destination. The techniques we use to find arc length can be extended to find the surface area of a surface of revolution, and we close the section with an examination of this concept.

Appropriate Integrals

In mathematics , an integral assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinitesimal data. The process of finding integrals is called integration. Along with differentiation , integration is a fundamental operation of calculus, [a] and serves as a tool to solve problems in mathematics and physics involving the area of an arbitrary shape, the length of a curve, and the volume of a solid, among others. The integrals enumerated here are those termed definite integrals , which can be interpreted formally as the signed area of the region in the plane that is bounded by the graph of a given function between two points in the real line. Integrals may also refer to the concept of an antiderivative , a function whose derivative is the given function. In this case, they are called indefinite integrals. The fundamental theorem of calculus relates definite integrals with differentiation and provides a method to compute the definite integral of a function when its antiderivative is known.

Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. It only takes a minute to sign up. I've noticed the following things while studying calculus, and would like experts to tell me if my conclusions are right. Why or why not? This observation holds for all balls, cubes, and simplexes provided they're centered at the origin.

You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up. Solid of revolution between two functions leading up to the washer method. In about , the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original charcoal.

Volume by Rotating the Area Enclosed Between 2 Curves

Сьюзан осторожно приоткрыла дверь и посмотрела на глянцевую, почти зеркальную стену шифровалки. Узнать, следит ли за ней Хейл, было невозможно. Нужно быстро пройти в кабинет Стратмора, но, конечно, не чересчур быстро: Хейл не должен ничего заподозрить. Она уже была готова распахнуть дверь, как вдруг до нее донеслись какие-то звуки. Это были голоса. Мужские голоса. Они долетали до нее из вентиляционного люка, расположенного внизу, почти у пола.

Она стояла у второй входной двери, что была в некотором отдалении, прижимая сумку к груди. Она казалось напуганной еще сильнее, чем раньше. - Мистер, - сказала она дрожащим голосом, - я не говорила вам, как меня зовут. Откуда вы узнали. ГЛАВА 74 Шестидесятитрехлетний директор Лиланд Фонтейн был настоящий человек-гора с короткой военной стрижкой и жесткими манерами.

Беккер увидел ждущее такси. - Dejame entrar! - закричал Беккер, пробуя открыть запертую дверцу машины. Водитель отказался его впустить. Машина была оплачена человеком в очках в тонкой металлической оправе, и он должен был его дождаться.

    Area of a Surface of Revolution The area between the curve and the x axis is the definite integral. The new applications to volume and length and surface.

    Applications to Area, Arc length, Volume and Surface area. Suppose f(x) ≥ 0 on [a, b]. Then it is clear from the definition of Definite integral that the area.
