The book arrived in excellent condition, and I find that it well written and fairly good explanation of the included mathematics. The book covers several different areas and topics of mathematics utilized in physics but is not a comprehensive mathematics book. There are several topics and details that I found that I didn't learn in the course I took 20+ years ago and appreciate that proofs are not the emphasis.<br>Someone with a fundamental understanding of calculus and mathematical notation would be able to follow most things in this book.
