Title: Weak In Calculus Theory
Product review: I don't expect a beginning level calculus text to have all the rigor necessary to develop calculus with precision. I do expect, however, that the author of such a text be honest and tell students that the mathematical precision necessary for the course is only appropriate at higher level courses. What bothers me greatly about this text is that it purports to be rigorous, complete, and precise. I am writing this review to tell you that it is not! It has many problems in theory, especially in the third semester. Here is one example of the sloppiness in the text. The text claims that a "parametric curve" is a set of points in the coordinate plane. This is not correct. This is the definition of a "graph." A parametric curve is supposed to be defined as a set of points in the coordinate plane TOGETHER with a set of parametric equations that generate the points.
