DISCUSS: Cofunction Identities In the right triangle shown, explain why v=(/2)u. Explain how you can obtain all six cofunction identities from this triangle for (0u/2) Note that u and v are the complementary angles. So the cofunction identities state that a trigonometric function of an angle u is equal to the corresponding cofunction of the complementary angle v .
DISCUSS: Sinusoidal Curves The graph of y=sinx is the same as the graph of y=cosx shifted to the right 2 units. So the sine curve y=sinx is also at the same time a cosine curve: y=cosx-2. In fact, any sine curve with a different horizontal shift, and any cosine curve is also a sine curve. Since and cosine curves are collectively referred to as sinusoidal. For the curve whose graph is shown, find all possible ways of expressing it as a sine curve y=asinx-b or as a cosine curve y=acosx-b. Explain why you think you have found all possible choices for a and b in each case.
