Discovering the concept of Derivative

The green dot indicates the numerical value of the slope of the curve. Checking the box- ShowDerivative will give you derivative function and the graph of that function in red. You can manualy move the x value of the point on the graph of the function by moving the point on the bar at the top center of your screen, or you can click the show animate-on button on the right. Stop the animation by clicking the Stop Animation A button. Remove the green curve by clicking the remove trace button. You can drag the graph of the function around to see how the function changes. You can type in other functions to observe their graph and concider their derivatives.
