# An introduction to the washer method in studying the integral

Generalizing the washer method | applications of definite integrals | ap calculus ab | khan academy washer method rotating around horizontal line (not x-axis), part 1 integral of (-1)^x. By allowing the thickness of each washer to become very small and summing up the volumes, we obtain the definite integral representation for the washer method: for a solid of revolution generated by revolving a region about the y-axis, the inner and outer radii are functions of y. The washer method defined the washer method uses the shape of a washer to help us find the volume of a shape created by rotating two functions around the x-axis a washer is a little piece of hardware that is used in construction and building projects it is made out of metal and is in the shape of a flat donut.

Two disk/washer method problems (given a diagram) again, i used a horizontal slice, except this one was a washer my integral was $$\pi\int_0^1 (1-y)^2 - (1-\sqrt{y})^2 dy$$ disk/washer method and shell method hot network questions how can my creature keep sand out of its mouth.

## An introduction to the washer method in studying the integral

Expand your knowledge on the washer method in calculus by using these handy tools understand how to find the area of a washer identify the integral to find the volume between two functions.

In this section, the first of two sections devoted to finding the volume of a solid of revolution, we will look at the method of rings/disks to find the volume of the object we get by rotating a region bounded by two curves (one of which may be the x or y-axis) around a vertical or horizontal axis of rotation.

Applications of the definite integral volumes of solids of revolution volumes of solids of revolution the axis of revolution is not a boundary of the plane region and the cross sections are taken perpendicular to the axis of revolution, you use the washer method to find the volume of the solid think of the washer as a “disk with a. Introduction to integration integration is a way of adding slices to find the whole integration can be used to find areas, volumes, central points and many useful things after the integral symbol we put the function we want to find the integral of (called the integrand).
