Use in conjunction with the corresponding student activity. Drag the sliders to change the quadratic function. Click on the check boxes to show the slope of a tangent at a point on the graph, to show the value of the derivative at that point and to show the derivative of the function. Move the point A and watch the shape traced out by the slopes of the tangents. Do the slopes follow a predictable pattern?
