George Arfken’s original publication, “Mathematical Methods for Physics” is in this reviewer’s opinion, one of the most comprehensive textbooks of this topic and an excellent reference source for engineers and physicists. It has gone through several editions with the additional authors, first  Weber and now Harris. Although I have and use Arfken’s first edition, this 7th edition has additional material and is consistent with the intent of Arfken’s original text. I recommend this text to any engineering student at the college or university level as it will assist them in their studies and provides an excellent approach to solving problems or explaining topics found in electrical engineering, mechanical engineering, and physics. The book will also be useful when the engineering student is confronted with problems in lecture that may not be clear in their class room text.
