Review title: Not worth the money
Product review: Perhaps this book would suffice as a surface reference, but it should not be used as the primary text for any course. The coverage is sparse at best, and it seems unlikely that anyone who didn't already understand the topics covered could do so with this book alone.Perhaps it serves a purpose, but it cannot be used extensively.
