<p>As far as I know, early transcendentals merely indicates that the author introduces transcendental functions (such as trigonometric and exponential functions) toward the beginning of the text as opposed to after integration, as most other textbooks do. As for which is better, I doubt there is noticeable difference, to be honest.</p>
<p>I would also like to recommend searching for an older edition on eBay or a similar website. Besides the obvious economical incentive to do so, textbooks are often “dumbed down” over the years, and I have heard this is especially true with Stewart’s book.</p>
<p>Single Variable: BC Topics
Multivariable: Semester III of calculus, not on BC exam.
Early Trancendentals: The things that students learn in Calc BC are normally taught as a separate, second semester in college. Early Trancendentals means that the BC only topics are taught alongside the AB and BC topics. This is a better version for BC, easier to learn.</p>
<p>So for Calc BC, you want to get a single variable early trancendental book. I recommend the fifth edition because it’s much cheaper and is pretty much the same with the exception of some problems. </p>
<p>Learning calculus from stewart’s textbook is horrible though. My calc class uses it and we only use it for homework problems. I tried reading from it once and it was a painful experience. Not sure if there is a better calculus textbook, maybe someone else can recommend.</p>
