Proof by Induction

Synopsis
This series of booklets is designed to give a thorough grounding in Inductive Proof. A good understanding in this topic is essential for all those people who wish to go on and study Mathematics and other science subjects like, Physics, Chemistry and Engineering.
Often the fundamental concepts like these are frequently not completely understood leading to confusion and often dissatisfaction and can result in people giving up on the subject altogether.
This is a shame because such confusion can often be attributed to poor teaching or unexplained misconceptions. This series of booklets sets out to explain fully and clearly every step throughout with everything presented in an easy to understand format.
There are a sufficient number of examples in this booklet to cover most types of questions that the student is likely to encounter.
All booklets in this series are competitively priced
