Two integers, a and bhave different signs. The absolute value of integer a divisible by the absolute value of integer b. Select the pair of Integers that fit this descriptionThen decide if the product of the integers is greater than or less than the quotient of the integers.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.
