Title: Step into readers' shoes.
Review: The best recommendation to the writers of textbooks is "Step into reader's shoes." Writer is an expert of the subject. He knows the subject very well. Readers are not. Readers need enough guide to follow what is written in the book. This book often jumps into a conclusion without enough intermediate steps. Equations come out of blue. I was perplexed by that the writing is sparse and crude. Thus I stopped reading this book and returned.
