McKeague and Turner (both, Cuesta College) cover the usual introductory trigonometry topics the six functions, right triangle trigonometry, radian measure, graphing and inverse functions, identities and formulas, equations, triangles, and complex numbers and polar coordinates. Appendices also review

"The examples in this text are well done. Students are very frustrated when too many steps are left out of an example, but these seem to present their reasoning pretty clearly. In Section 4.3 (graphing with phase shifts) the examples are well constructed and worked out. I appreciate how they start by showing lots of detail and eventually, as you progress through the section, the information is boiled that [sic] down to the essential data -- which is what we want students to be able to do.... The greatest strengths in this text are its coverage of graphing, the right triangle approach to the development of the trig functions, and the organization of the examples (with line by line explanations of the step being performed...It really helps students follow the process if there is 'narration' to what is going on."
