Title: Practice Problems
Review: I it is a new book. It does not look like he finished working on it before it went to press. Many chapters have a blank page with the words 'There are no proctice problems corresponding with Ch. 2 ...". I have not had the time to go through it all, but I have found quite a few errors. For example Ch 61 Practice Problem #1 the correct answer is 78.23 km He forgets to multiply by 2 for the correct distance. The formula is d = sqr(17h) he aproximates this and uses d = 4.1 sqr(h) which is fine but he does not use the formula correctly.The book will be much better after the he corrects the many errors.
