<p>my math class is going to start using a new text:( we are going from the 4th edition to the 5 edition. I contacted the prof. but didn't get a response. What do you think I should do?</p>
<p>get the new edition (???)</p>
<p>Well, in general how unique is one edition to the next in math books? (I think about that, but dont want to spend $110 on a math book)</p>
<p>Usually if you are in the middle of the sequence, they won't require you to buy the new book (or at least it's how it worked at my alma mater). To answer your question, the material is basically the same from edition to edition. The main difference is in problem sets. I'd take my old edition to the bookstore and see if the problem sets are the same or if there is some logical way as to how they have rotated. </p>
<p>They changed the calc books 3 times during my undergrad tenure, I had to buy two calc books, but I bought the second one used because I already had a decent one that was new when I bought it. Try amazon.co.uk along with the usual suspects. I've found even with shipping, select books are cheaper on amazon's uk site.</p>
<p>usually the differences between editions is minor... maybe a few mistakes fixed and the order of the problems switched up at the end of a chapter. Maybe sit down with your edition & the new edition and figure out if it'll be a problem. If the teacher has problems assigned out of the new addition, you'll just want to know if you're doing the correct problem.</p>
<p>Well, this is actually for the fall. If I could find the new edition cheapr somewhere, it woukd be great.</p>
<p>This quarter, I had to buy the OLDER edition of my physics text. I was using the 7th edition (newest), but apparently since this was at a different school I need the 5th instead. I ended up buying the 5th edition off of half.com for like 30 bucks, because all of the problems were changed. I'm a physics major anyway, so I guess having an extra physics text won't hurt ;)</p>
<p>Look on half.com, Amazon Marketplace, and eBay for cheap texts.</p>
