Calculating area graphically on the HP50g appears inaccurate

[cdecastro]

Thanks for the reply Han. Of course, I understand your point. My issue is that if I perform the integration (numerical or otherwise) using the limits found by ROOT I would expect the value to agree (to the limits of accuracy of the device) in both contexts. I.E. I would have gotten the same numerical value using the AREA function as I would using the calculators numerical integration procedure.

Thanks,
Chris
