More Application of Trig Functions

Angle of elevation and angle of depression
Distance and Bearing
- Two ships
Arc length
- Given angle in radians, determine length of arc (ala satellite distance traveled)
- Given angle in degrees, determine length of arc
- Given arc length and radius, determine angle
- Arc length traveled over a certain amount of time.
Area of Circular Sector
- Given angle and radius, determine area of sector (ala lawn sprinkler or windshield wiper)
- Given area and radius, determine angle
Velocities
- Angular velocity (ala grandfather clock)
- Fixed angular velocity related to linear velocity for different radii
- Linear velocity (ala satellite speed or various diameter bicycle wheels)
  - Bicycle wheel/gears would be a nice place to use an interactive app...
- Nice app dealing with linear velocity of persons at various latitudes
- RPMs for fan blades or lawnmower blades or propellers given angular velocity in some form.
