We have a ladder sliding against a vertical wall and against a horisontal ground. Pick out a fixed point P on the ladder and find a mathematical model (expression) that describes the path that the point P will follow when the ladder is sliding. Control Objects: - Path : Show a part of the curve - Ellipse : Show the whole path (ellipse) - P Midpoint : Set the position of point P to the mid point of the ladder - Txt : Show the length of the two parts of the ladder - Formula : Show the ellipse formula - Move Point : Move the point P on the ladder - Move Ladder : Move the ladder (sliding against the wall and the ground) - Info : Show information and the explanation of the curve as an ellipse |
