Derivative Plotter

This sketch shows a function with a tangent line at point A. Point B in the sketch plots out the slope values of the tangent line, so it follows the path of the derivative function.
Using the Move tool, slide point A along f(x) to see point B trace out the derivative of f. You can also look at other functions by double clicking on f(x) in the algebra pane and entering a different function rule.
