input:  Now, answer this question: Title: A good supplement Review: If you are not already in a calculus class and are well versed in the terminology, you may find yourself a little lost with this one. This book assumes that you understand integrals and other mathematical theories. I would not use this to teach myself about Laplace transforms.As a supplement, this is a fairly good book. As with most books in the series, there are various step-by-step instructions to show you how these work and to explain the various functions and theories. There are supplementary exercises at the end of each chapter with the answer right there for you to test yourself. Is this product review negative?
