Suppose that cos(0) = and 0 <0 <. a. Sketch a right triangle with an interior angle measure of 0 radians. Since cos(0) = , you can write down the lengths of two sides of the right triangle. 29 > b. Using your diagram from part (a), determine the exact value of sin(0). Enter your answer as a fraction. sin(0) Preview c. Using your diagram from part (a), determine the exact value of tan(0). Enter your answer as a fraction. tan(0) Preview Consider the right triangle shown below. The hypotenuse of the triangle is r = 13 cm long. Suppose cos(0) side lengths of the triangle? = 0.784 and sin(0) = 0.621. What are the other cm Preview • y = Preview cm

Refer to the following figure in answering Exercises 7 through 13. It may be helpful to sketch figures.When side y=side r. a. What is the value of the sine function? b. What is the value of the cotangent function? c. What is the value of the cosine function? d. What is the value of the cosecant function?

Evaluate the sine and cotangent functions at the quadrantal angle 32.
