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 conceptually introduces the concept of the derivative, which is one of the central topics in Calculus. The derivative is introduced by way of a discussion of real-world experience with position, velocity, and acceleration in everyday life. The position, velocity, and acceleration graphs are drawn to illustrate the point and numerous example problems are worked to reinforce the material.
