N2  - This worktext was written in style that will appeal to any college student taking trigonometry. Some level of mathematical maturity is required, especially on the functional and analytical part of the text. To help both the students and teachers, the authors prepared a wide array of exercises with different difficulty levels, specifically designed to reinforce the earlier lesson, and sometimes, to introduce the next topic. The inclusion of spherical trigonometry at the latter part of the worktext is designed for engineering students. While it is not a required topic for non-engineering students, it can serve as an enrichment topic or as an advanced topic for exceptional students." -- The authors
