Question: Review: I bought it before I knew anything. Now that I have been training a bit more and reading more I realized that this book is lacking a whole lot. I do not really recomend this book unless you can get it for free. 
 Polarity: Negative

Answer: True


Question: Review: I bought this book for my book club and I have had a very hard time reading it. The characters are too life-like in my opinion for me to have any sympathy towards them. I have read other novels from the Victorian Period that I have liked, but this one seems overly wordy and dull in my opinion. I gave two stars instead of one for the mini novel Indian Summer of a Forsyte, the best part of the series, which saved this from a one star reveiw. It was touching and beautiful to read. If only the rest of the books followed such a formula. 
 Polarity: Positive

Answer: False


Question: Review: [..]Let me warn all potential customers that this book is all about quantity of material instead of quality. While the book does cover such advanced topics as Fourier Analysis and intro to Partial Differential Equations, the book lacks sufficient examples about what is being said (a number of sections have no examples at all).I did find the most well-written sections to be the application of second-order differential equations (applied to spring oscillations etc.) However, as far as getting a bang for your buck, I HIGHLY RECOMMEND Morris Tennenbaum and Harry Polland's Ordinary Differential Equations Dover edition (cheaper, and MUCH MORE effective. Trust me). 
 Polarity: Negative

Answer:
True
