Derivative Calculator website - give it a try, does it help you conceptually seeing the graphs?

A very cool site I just became aware of is called Derivative Calculator. You can type in any function, and it will provide the derivative function and both graphs. Not only that, it will find roots of your function, and also show steps of how it got the derivative. It can find higher order derivatives, as well!

This could be really useful for any of us to gain further conceptual understanding of derivatives, as well as allow us to check ourselves with more complex functions, or simply find the derivative of really complex functions we don't see in classes. Try it out!!
