Talk:Fundamentals of Calculus, Special Relativity and Quantum mechanics/Derivatives

The graph of the derivative of the absolute value function which was on the first draft of this page is inaccurate. The slope of the graph is +1 for x>0 and is -1 for x<0, but the graph here shows that the derivative is equal to +1 and -1 for x>0, and undefined for x<0. As such, I've removed the image from the page. Here is the original filename:
