Chapter 1, Problem 109(choose chapter or problem)
In later chapters we will study trigonometric functions of angles other than quadrantal angles, such as 15, 30, 60, 75, and so on. To prepare for some important concepts, provide conjectures in each exercise. Use a calculator set to degree mode. The angles 15 and 75 are complementary. Determine sin 15 and cos 75. Make a conjecture about the sines and cosines of complementary angles, and test this hypothesis with other pairs of complementary angles.
