The book was engaging in the fact that in presented challenging problems and helped the reader work through them but by chapter 10 I just couldn't take all the errors and had to put it down. There are numerous misprints for example problem 5.8 They set the problem up correctly but then clearly wrote the wrong answer (56,000 x 0.05 is not 2300). They misprint the number 34 with a 134 in problem 5.12 but then solve correctly, 5.17 they subtract m2g from m2a incorrectly but the next line reverse it. problem 5.19 when taking the derivitive of a sin they write the answer as sin, but the next line change it to cos. This is all very confusing if you are just learning the material, and the mistakes are everywhere. It becomes very time consuming to check and recheck answers just to find the book was wrong. This is the first schaum's outline I bought and will not buy another.
