This applet is a graphical representation of the derivative at a point.
Drag the sliders to change the point of tangency (a) and to bring a general point on the graph toward the point of tangency (x). Use the checkboxes to observe how the vertical and horizontal difference between points is related to the equation for the definition of the derivative.
