Are trig functions covered in the text? If so, can the trig material be easily omitted?
A Short answer: yes and yes. Trigonometric functions and models are covered in a self-contained chapter (Chapter 9 in the Calculus book and Chapter 16 in the Finite Math and Calculus book). This chapter can be taught in its entirety anytime after the chapter on the integral. Alternatively, individual sections of the trig functions chapter can be taught earlier to achieve a thorough integration of trig material in the course. (For instance, the first section can be taught along with non-linear functions, the second section can be taught along with the derivatives material, and the third section along with the integral.) If you choose to omit trigonometric functions, simply omit that chapter.
