Subject: Table View of Limits Applet
Tom,
I am planning to use some of the applets from your wonderful website in my
calculus course this semester. They are great and will clearly be very
helpful for me and the students.
I have one question. On the applet titled "Table View of Limits" if I
change the function...

The tabular view of the second derivative is a bit confusing, since it isn't clear which interval the average should be computed over. Maybe leave out the f(x) values, just showing f'(x) values at specific x values and then doing the obvious computation for the second derivative.

Conditional expressions think that the derivative exists at join points, even when the result should not have a derivative.
