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 introduces the concept of the improper integral. These types of integrals have one or more limits of the integration occur at infinity. Many problems are solved that teach the student how to properly solve integrals of this type.
