<p>Is there a lot of difference between each new edition of a textbook? For example, 21-123 Calculus requires Stewart's Calculus Early Transcendentals 7th Edition, and 33-107 Physics II for Eng. Students requires University Physics 12th Edition, but I already have the 5th and the 11th. Should I buy the new editions? Or can I get along with the older editions? Would I have trouble doing homework etc. because of the amount of new exercises added to the new edition??</p>
<p>I can’t even find the 7th edition on AMAZON, and the picture of the book does not look like the 6th edition to me. It looks like:</p>
<p>[Amazon.com:</a> Essential Calculus: Early Transcendentals (9780495014287): James Stewart: Books](<a href=“http://www.amazon.com/Essential-Calculus-Transcendentals-James-Stewart/dp/0495014281/ref=sr_1_5?ie=UTF8&qid=1249261634&sr=8-5]Amazon.com:”>http://www.amazon.com/Essential-Calculus-Transcendentals-James-Stewart/dp/0495014281/ref=sr_1_5?ie=UTF8&qid=1249261634&sr=8-5)</p>
<p>Which doesnt even have an edition number on the page. Its older than the 6th edition? Also, the ISBN number matches ^that book.</p>
<p>Thats the one I bought (21-120). Honestly though, I dont really know.</p>
<p>I’m thinking of buying an international version, because I’m thinking it’s not worth spending so much on an eight week mini-course, especially something I covered way back then when I was studying for Calc. BC with the 5th Edition. </p>
<p>[[???]Essential</a> Calculus : Early Transcendentals (Paperback)](<a href=“http://foreign.aladdin.co.kr/shop/wproduct.aspx?ISBN=0495556203][???%5DEssential”>알라딘: Essential Calculus : Early Transcendentals (Paperback)) The ISBN is different, but I think this is it…</p>
<p>Anyways, do the books change a lot with each new edition? That was my main curiosity.</p>
<p>My class isnt a mini course.</p>
<p>Honestly, I dont know. I would email the professor to see if you can get by with an older book.</p>
<p>I was told not to buy the international edition even if the seller says that they are the same.</p>
<p>Why? Is the international edition different?</p>
<p>Where does it say which books we need for each class? Because on ScheduleMan it says that they are not listed yet.</p>
<p>Try the CMU bookstore. Any answers though?..Dunno if I should take my old books with me. How much do the professors use the textbooks for Calculus and Physics?</p>
<p>For physics, you will probably need the 12th edition because they assign problems right out of the book, and it’s not their fault if you did the wrong problems. Also, that book can be used for Physics I and II. However, if you can find a friend and see that they correlate, you can manage. Also, you’ll need Stewart’s 7th for Calc in 3-D also. Some profs use websites to submit homework, but some require you do the problems in the text. </p>
<p>Do not buy a book for 15-110 or 15-120 (intro and advanced java programming).</p>
<p>You could always buy an old edition of the book and go to the library and scan in the homework problems from the course reserve copy.</p>
<p>Also, I had no problem using international versions through undergrad. If you’re buying this book to keep it (plan on going to grad school or use it as an engineer) I’d recommend being sure the book is hardcover. I’ve got a few softcover books and they just don’t hold up nearly as well as hardbacks.</p>
<p>
</p>
<p>I second that. Softcover books fall apart pretty quickly after a while and, if you are planning to go to grad school, you may want to keep your textbooks, especially basic math and physics, long after you graduate.</p>
