Derivation of the Derivative

Here's how to use this applet

To reset, click the top-right corner.

The function f can be changed to anything you like! Just type f(x)= ... into the input bar at the bottom.

The point A can be moved by clicking and dragging. Or, in the input bar, you can type in A=(x, f(x)) for whatever value of x you like. But then, it might not drag anymore; reset the construction.

The point B is determined by A and delta-x. Use the red slider to change delta-x. To find a particular value, type delta-x=... into the input bar at the bottom. You can get the delta character by clicking the far-right side of the input bar.






Oops! You're not seeing a graph! Check your message bar at the top of the screen; make sure ActiveX controls are enabled.
