This book, in one word, is a greatOne! The text mentioned in this book is simple yet like a poetry; once you read a line you want to read the next one.... great book by the IMO India coach BJ venkatachala !

The book is great. Bj Venkatachala does an excellent job of explaining functional equations to even the beginner at the topic. Explanations are easy to understand and the problems in the exercises are of a good level.I recommend this book for Rmo and other olympiads, or even for some math fun

Good

it is the best book for functional equations. functional equations are not commonly teach at schools. it is also used for self learning. the author of this book was an olympiad trainer (teacher).
