Review for test. Before class today, please work the following problems, which constitute a sample test:
§14-1 #1, 5, 11, 25
§14-2 #15, 17, 26
§15-1 #3, 5, 11, 21.

Answers to all of these problems except for #26 are in the back of your book. Here is a solution to §14-2 #26, but don’t peek until you have tried on your own!

Look at RHS to see a denominator begging to be rationalized. Start with RHS and multiply both numerator and denominator by (sec q + tan q) to get (sec q + tan q) / (sec² q – tan² q). Now tackle the denominator by itself as 1/cos² q – sin² q/cos² q, which is easy to evaluate since we already have the c.d., namely cos² q. Perform the fractional subtraction to get (1 – sin² q) / cos² q , which simplifies to cos² q / cos² q = 1. If the denominator of the RHS is 1, then the RHS is simply (sec q + tan q) / 1 = sec q + tan q as required. (Note: We did this same problem in class on Wed. 5/10 using a slightly different method. Check your notes and compare. Several methods are usually possible for each identity proof.)
