This text is written for undergraduate and even graduate chemistry students who need a quick review of the mathematical methods that are used throughout chemistry. It is the outgrowth of a collections of Math Chapters from McQuarrie's famous texts, Physical Chemistry: A Molecular Approach and Quantum Chemistry, Second Edition (2008). These Math Chapters provide students with concise reviews of mathematical topics, discussing only the minimal amount that students need to know. By reading these reviews before the math is applied to physical chemistry problems and concepts, a student will be able to spend less time worrying about the math and more time learning physical chemistry. Key Features: 1. Can be used as a supplement with any traditional textbook on pchem or quantum chemistry 2. Focuses on clear, mathematical descriptions, written by a chemist for chemists 3. 23 short chapters, each one designed to be read in a single sitting 4. Presents material at a practical level with an emphasis on applications to physical problems 5. Examples illustrate the techniques being discussed 6. 600 problems, most of which have answers in the book
