Description: 
Solving sine equations. This shows a sine curve that can be manipulated and a horizontal red bar that moves up and down. Students are given equations to solve, like sin x = .5. They graph sin x and then put the red bar at .5 and find how many solutions there are in the given range. No feedback is given, so students won't know if they have the right answer.
