5 stars (A gem. But beware of Amazon bugs!) - I reported them to Amazon months ago - nothing's changed. There are two different books on amazon.com: BOOK 1: "Precalculus 5/e" by Larson & Hostetler (search for 0618052852 on amazon.com). It has a very good supplement - "Study and Solutions Guide" by Dianna Zook (0618072713). Both books were published by Houghton Mifflin Company, which has nice resource site http://college.hmco.com/mathematics/students/. I have no affiliation with this publisher. From the pull-down "Precalculus" window Select Title "Precalculus 5/e Larson/Hostetler ((c)2001)". You'll be very pleased with the links you find there. If you seriously want to ace Precalculus - get both - "Precalculus" and "Study...". BOOK 2: "Precalculus Functions and Graphs: A Graphing Approach/Precalculus With Limits: A Graphing Approach (Student Study Guide)" by Larson (0618074104). Here's one bug: Somehow reviews posted for BOOK 1 got mirrored onto BOOK 2 or vice versa (compare books' reviews). Another bug: Book 2 in reality has a title "Study and Solution Guide" and its authors are Bruce Edwards and Dianna Zook (not Larson). Compare it with "Study and Solutions Guide for Precalculus Functions and Graphs : A Graphing Approach and: Precalculus With Limits : A Graphing Approach" (0669417297), which is older: 2/e, (c)1997. Book 2 gives solutions to odd-numbered excersizes and to all Chapter Practice Tests and to Chapter and Cumulative Tests in both "Precalculus Functions and Graphs...3/e" (0618052909) and "Precalculus with Limits...3/e" (0618052917). Those two books were published in 2001 by Houghton Mifflin Company. On http://college.hmco.com/mathematics/students/ from the pull-down "Precalculus" window select either of their titles. Click on "Purchase this Product or Study Aides" and you'll see the whole learning package which includes aforementioned "Study and Solution Guide" ISBN: (0-618-07410-4) (for some reason Bruce Edwards is dropped and only Dianna Zoo...
