Corrections to Trigonometry Demystified, 2nd edition
On page 389, Final Exam Questions 97 and 98 both have two correct answers! The answer key specifies choice C only in both cases. However, choice B will also work. Please give yourself credit for a correct answer either way.
The questions ask what happens to the term values in the series expansions. In both instances, you can interpret this expression to mean either the value of the series in terms of partial sums, or the value of each term considered by itself.
For explanations of the answers to all 100 exam questions in this book, you can watch over five hours' worth of videos on a YouTube playlist. Enjoy!
