The Calculus Tutor covers all of the core topics in detail. What sets this series apart is that 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. Students will be able to work problems with ease, improve their problem-solving skills and understand the underlying concepts of Calculus. 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.
