Hi - I've been fumbling my way around the HP34S keyboard (and manual) for a few days. Pretty much found everything that I need to use (matrices, complex number math etc).
The only thing I have not been able to find is how to enter either 2 value (X,Y) data pairs or (X,F) data (i.e. a data value and its frequency). I've tried pushing X then Y (and Y then X) on the stack and pressing 'A' (i.e sigma +),but that does not seem to work.
I've found the corresponding functionality on the HP30B described here:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c02038743
which seems to indicate that the calculator has to be switched explicitly into different data entry modes, but have not been able to find the corresponding data entry options on the 34S. I'm guessing that the X,Y data entry would be common to the linear regression function..,
Can anyone point me in the right direction here?
Many thanks,
Nick
