Question

Assessment
Using complete sentences, define and compare radian measure to degree measure. In doing so, be sure to answer each of the following questions:
When would degree measure be appropriate?
When would radians be a better choice?
What are the pros and cons of each?

Answer 1

Adam and Beth are visiting an amusement park and have decided to ride the carousel. Adam picked a horse on the outside edge and Beth chose a dragon on the inside, closer to the center.
Part 1: Do Adam and Beth travel the same distance during the ride? Choose a distance that each seat (horse and dragon) sits from the center and use the radius to determine how far each would travel during one rotation.

Part 2: Choose an angle of rotation. Using complete sentences, compare the distance Adam and Beth will travel during this angle measurement.

Part 3: Using complete sentences, describe which position you would prefer and why.

Robbie the Robot is on a weather satellite orbiting Earth about 3600 km above the surface. The Earth’s radius is about 6400 km. He has had a malfunction in his output device, and the satellite is traveling without communication. His last report was only in terms of trigonometric values and was only partially received. It said, sin Θ < 0….. and then he was lost again.
Part 1: Create a set of coordinates that would be reasonable for Robbie’s position in space and satisfy his last, partial report. Using complete sentences, describe Robbie’s location and your reasoning.

Part 2: What are the values of the sin Θ, cos Θ, and tan Θ using your coordinate point?

Answer 2

yes why

Answer 3

dont know what you mean 2b though

Answer 6

no help :(

Answer 7

With degree measure, you are stuck on the ferris wheel - forever circling. If you want to break free, and go anywhere you want, you'll have to use radians.
