<p>does anybody know about the calc book being switched to a different version for this upcoming year? one penn student told me. he wasn’t 100% sure though. thus, i wanted to make sure.</p>
<p>i think the isbn is 55457263. they changed the book last year and they're still using stewert's book for the summer. i guess they wont change next year. email somebody who teaches math 104 in the math department and they should be able to confirm u.</p>
