textbook for math 31

<p>I have a question about the textbook for Math 31. I've been researching half.com, ebay, barnes and noble, etc to buy my textbooks and there seems to be two different 5th versions of Calculus by Stewart: Single Variable and Multivariable. Which one is the right one for students in Math 31?</p>

<p>31 should be single variable...but why not buy the extended one?</p>

<p>There are several kinds of Stewarts Calculus 5th edition. I suggest you find the right ISBN number. There is a version that has 'early transcendentals'. There is one book that has single and multivariable combined, and one that has just single and one that has just multivariable. The chapters and problem numbers differ from book to book. So be aware of that.</p>

<p>The combined one is pretty heavy. I remember the whole class was pretty annoyed by the fact that we all had to carry the heavy combined version while the instructor carried the thinner multivariable version.
You might also want to check out the solutions manual. I used the one that had both odd and even solutions. Definitely check that out. There was a copy for sale on Ebay for $60... but that was two years ago. It's extremely tough to get a hold of one of those.</p>

<p>i had the combined one. its worth it if you're going to take 31a, 31b, and 32a since you use the same text for all vs having to buy all the separate editions (and taking a loss when selling each one too). i believe the ISBN they recommend is the combined edition anyways. </p>

<p>you dont really have to carry it anywhere unless you want to. the text is never needed in lecture. in discussion, your TA will have his/her own copy to use (although some students bring theirs along too). the only time you need it is for doing homework and studying.</p>

<p>oh yeah, my professors usually only assigned odd problems so you can check your work on your homework, since the SSM only has odd answers. a teachers SM (with odd and even) would be helpful for extra practice problems when studying, but usually wont help with homework.</p>
