A) Convert to radians: Express your answer as an exact fraction of B) Convert to radians: Round your answer to three decimal places
C) Convert to degrees: Give an exact answer with no approximation
D) Convert to degrees: Round to the nearest hundredth of a degree
E) Find the exact value without using a calculator: F) Find the exact value without using a calculator: G) Given the following information, find the exact values of all six trigonometric functions:
, H) Determine the amplitude, period, and phase shift. Graph one complete period: I)
Graph at least one complete period: J) Graph at least one complete period: K) Graph on one set of axes. Set your scale to be sure
and to include at least one complete period of each function.
L) A child has tied a rock to the end of a 3 foot long string. He is spinning the rock around in a circle at a rate of 4 revolutions per second. What is the linear speed of the rock, in miles per hour? Round to two decimal places.
M) A calorie­counting smartphone app will compute the number of calories in a slice of pizza, but only in terms of the number of square inches. You estimate that the pizza you are eating has a diameter of 24 inches, and your slice takes up about 75°. How many square inches is that slice? Round to two decimal places.
