RE: How to evaluate f'' at a specific point?
I would just do

diff(diff(3ROOT(x-2),x),x) and then
Ans|x=1.99 (Ans actually has to be copied explicitly from the command line above)

returns 478.76 . . . for me.

Or do you have to do it with the d/dx template?

[You can also define f(x):=3Root(x-2), and then simply type f''(1.99) also returns 478.76 . . .]
