Calculus essentially takes the fundamentals of algebra and extends them to include rates of change between quantities. The concepts are taught entirely through step-by-step example problems of increasing difficulty. It works by introducing each new concept in an easy to understand way and using example problems that are worked out step-by-step and line-by-line to completion. This lesson teaches students how to apply the concept of the integral in order to calculate the volume of an object. Problems of this type involve a function that is revolved around the x-axis to make a three dimensional shape. The goal is to find the volume of this shape. The student is taught how to set up the problem and solve the integrals accordingly. Teachers User Instruction & Resource Guide - Includes Recommended books & Calculus Websites.
