The Mean Value Theorem is a key result in elementary calculus, taught in every first-year calculus class. ... this book is an interesting read for all mathematicians; it contains little known nuggets of information which could be useful for teachers to attract the interest of their students. (Phill Schultz, Gazette of the Australian Mathematical Society, Vol. 44 (5), November, 2017) This excellent source book on the MVT will provide a wide mathematical audience with insight into its history, proof, and place in mathematical pedagogy. ... This book will be an excellent choice for a capstone course for mathematics majors, an invaluable reference for any individual teaching calculus, or simply an enjoyable read for one who has completed calculus and wants to delve more deeply into the MVT and its history. Summing Up: Recommended. Upper-division undergraduates and above; faculty and professionals. (R. L. Pour, Choice, Vol. 55 (2), October, 2017) The book under review discusses the evolution of the mean-value theorem and of some of the concepts behind it. ... the present volume is concerned with some mathematical and historical aspects related with the mean-value theorem. The author provides detailed and rigorous proofs of the mathematical results and even includes original source material presenting the flavour of the history.
