The TI can! Enter solve, enter the d/dx, set where x equal to x, enter a guess for x, solve for x, and you get an answer for x when d/dx=0 which will be a min or max of f(x). The variable x now has the number that solve arrived at. If you type in the equation and enter it, you get the value of f(x) at that point. Nicely, since x root of y is available, answers are available for negative numbers where something like 3 root of x is involved.

lrdheat - thanks for the cool tip! I tried this earlier and it stayed busy for a while so I didnt think it would work...

I found these other related (undocumented) operations the TI36X can do:
- Use 2nd Integral in num-solve to solve for uppper, lower limits or even coefficients used in the expression.
- Both 2nd d/dx and Integral can be used in data/formulas and table/edit function --> gives numerical f(x), f'(x) and integral f(x) in the table(s)

Hi.

Got it figured out! Sorry for the mixup.
