The Schulz/Briggs/Cochran  Precalculus eText is available only in digital format via MyLab(tm) Math. To help students stay focused, and to provide a framework for further exploration, the authors have also developed a printed note-taking guide called  Explorations and Notes. The  Explorations and Notes can be packaged with the MyLab Math access code or can be accessed electronically within the MyLab Math course.
