Questions & Answers
Q: What is the disk method used for in calculus?
The disk method is a technique used to find the volume of a solid by integrating the crosssectional areas of circular disks along the axis of revolution.
Q: How do you determine the bounds for integration in the disk method?
The bounds for integration are determined by identifying the xvalues where the region bounded by the graphs intersects the axis of revolution.
Q: What is the significance of little R and big R in the disk method?
In the disk method, big R represents the distance from the far end of a rectangle to the axis of revolution, while little R represents the distance from the inner edge of a washer to the axis of revolution.
Q: How do you calculate the volume using the disk method?
To calculate the volume using the disk method, you need to integrate the equation of the function squared, multiplied by π, with respect to x over the specified bounds.
