A. Use the unit circle to find the exact sine and cosine values of each given angle. Then use your calculator to find a decimal approximation for each one (be sure to round to 4 decimal places). 1. sin(1350) = 2. cos(240) = 3. sin(-330) = 4. cos (-45) = B. Use the unit circle to solve the following equations. (Some equations have two solutions). 5. sin(0) = 1 6. cos(0) = -0.5 7. cos(0) = 2 V3 8. cos(0) = - For problems 9 and 10, you are given the cosine value for the endpoint of the arc corresponding with an angle of 0 degrees. For each value of cosine, do the following a. Indicate the two quadrants in which the angle 0 will terminate. b. Estimate the value of sin 0 for each of these points. 9. cos 0 = 0.15 10. cos0 = 0.91 11. The original Ferris wheel designed by George Ferris, had a radius of 125 feet. If a person boards the Ferris wheel from the bottom (ground level, ignoring seat height), how high above the ground is the person after traveling 2/3 of the way around the wheel? (Hint: sketch a diagram and label parts)
