I just wanted to say that I love your program! I was going to ask about making it easier to toggle the visibility status of a function, then noticed you've already done it for the next version! I'm an engineer turned math-teacher. I'm just finishing my student teaching, and I have used your program quite a bit to show students examples of everything from conic sections to the inverse relationship between exponential functions and logarithms. Being able to set up a list of functions ahead of time, then toggle them on and off using a wireless mouse lets me move around the classroom instead of being stuck at the board or the overhead projector. And if students have questions or suggestions about things to try, I just step up to my laptop and we give it a shot. It was particularly useful when I set up a file for a conic section ahead of time and had a set of points/lines to show the foci, vertices, aymptotes, etc of the different curves. Thank you very much for all your work.(Continue reading)
