This is the "early transcendentals" version of a text that was reviewed here earlier. Most of what was said in that review applies to this book also. The main difference is that the logarithm and exponential functions are introduced much earlier in this version of the text.
The need for an "early transcendentals" option is a consequence of the widespread adoption of the idea (first proposed, I believe, by Felix Klein in his Elementary Mathematics from an Advanced Standpoint, where he argues that it be used in the schools ) that the natural logarithm is best introduced as the integral of 1/x and that the exponential is best defined as the inverse of the natural logarithm.
Adopting Klein's suggestion was always a rather strange decision in the context of the average undergraduate calculus text. After all, no one felt the need to include a rigorous definition of the sine and cosine functions. Giving such a definition also requires doing some (rather hard) analysis, as one can see in Spivak's Calculus and in most standard real analysis texts. Furthermore, undergraduates arrive in college already "knowing" about these functions; it seems reasonable to simply recall their properties and use them, as we do for the trigonometric functions.
The approach taken in this book is less radical than that. The authors define a^{x} for rational x in the usual way (without bothering to prove the existence of nth roots, of course), then extend the definition to irrational exponents using a limit argument (with at least some proofs). They then define the logarithm as the inverse function, and finally use the limit of (1+r/n)^{n} to introduce the "natural" exponential function. (At this point of the text, not a word is said to justify that adjective!) The derivative of the logarithm function is obtained first, then the inverse function theorem is used to find the derivative of the exponential function.
This approach does have the advantage of introducing a serious example of the use of limits into what is usually a dreary chapter. (Until we meet the derivative, why do we care what the limit is?) I believe it is an improvement on the "late transcendentals" approach. But in the end I still have my doubts whether students are ready for this kind of analysis so early in the course.
For what it's worth, I would simply take for granted the existence of the logarithm and exponential functions and their basic properties. Then, using the definition of the derivative, it's fairly easy to prove that the derivative of a^{x} is some constant times a^{x}. Choosing the right value for a makes that constant equal to 1, which explains what is "natural" about e^{x} . An analogous argument explains why we must use radian measure if we want the derivative of sin(x) to be cos(x) rather than a constant times cos(x). This seems both simpler and more illuminating, even if it hides the inherent trickiness of defining these functions. There's time for that in the analysis course.
