Complete the following questions utilizing the concepts introduced in this unit.
1. Find the length of an arc in a circle of radius 10 centimeters subtended by the central angle of 50°. Show your work.
2. Graph f(x)=x sin x on [-4π, 4π] and verbalize how the graph varies from the graphs of f(x)= pm x .
Graph f(x)= frac{sin x}{x} on the window [−5π, 5π] and describe freely what the graph shows. You can use www.desmos.com/calculator to obtain the graphs.
3. A 23-ft ladder leans against a building so that the angle between the ground and the ladder is 80°. How high does the ladder reach up the side of the building? Show the steps of your reasoning.
