Query: Student who is required to use this book

This book though lucid in its conversational language does not explain how the author came to his conclusions. Gives examples that the solutions of which are not traceable to the method described and is dirth of the supposed answers to exercises included. As a required text it is a nightmare to an engineering student required to take this couse as a introduction to the subject.David M. Cook (actual name)
