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.
