Keystrokes for upper/lower in TI-83 + graphing calculator
Posted on 2007-07-27
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 =(
