Keystrokes for upper/lower in TI-83 + graphing calculator
Hiya,
Using the TI-83 plus edition calculator from Texas Instruments, would like to know what the keystrokes are to obtain the command which relates to the upper/ lower value of certain calculations..
eg the Tinterval command, which will calculate to give 2 values, .. in the form (-x, x).
I've seen this function being used in some programs, just appears as simply 'upper' and 'lower', which they then use to directly store as other variables or similar. Can't find it under catalog or anywhere else though =(

Nope, can't seem to find it in either of the pdf files..
I'm looking specifically for the command 'upper' and 'lower', which will output the respective upper and lower value of a calculation if there were two made.

Hmm, if it helps.. here's what a program that was made using these two commands looks like:
~
...
:Tinterval X,sqrt(N),N,(1-2C)
:lower->A
:upper->B
:Disp A,B
~
That results in the two critical values calculated from that command being stored under variables A and B.
