Mr. Gabriel,
I like your enthusiasm for math. There are some aspects of math that I would like to change also–in conics though, not calculus. I find your way of representing derivatives interesting. I have created a couple of graphs illustrating the classical (using h) and your new way (using m and n) for finding the derivative of x^3 at x=2. The first is a graph I sometimes used when I taught calculus to high schools students and the second might be used by future math teachers teaching your calculus. I would like to share these graphs with you. Do you have an email address that you don’t mind sharing with me so I can send them to you?
