Sketch the Derivative Function: Without Words
In the applet below, a function f is shown (black).
Its derivative function, f', is shown in green.
Feel free to input any function you'd like.
Slide the slider to see the physical meaning of the derivative of a function (at a certain input value: x-coordinate of white point) within this graphical context.
How can we sketch the graph of the derivative of a function? Explain.
