A blog is that is all about mathematics and calculators, two of my passions in life.
Thanks to the Calculator Store in Spain! :)This is a HP 50g, only in a blue case. Eddie
That is great. I think I may pick one up.
The CAS never heard of the normal distribution or the Gaussian error function. Integral of exp(-x^2)dx gets lost. I would expect better from HP. The power of the hardware is sufficient; Mathcad 2000 could do it on a PC, and the HP hardware is certainly equal to the PC's of 13 years ago.This is probably not the only flaw. In any case, HP is going more "mainstream" as shown by the 39GII, and the coming prime. They are converging to something like the TI Expire. Let us hope that HP calculators do not expire! They have been an important part of my computing environment since my first computer in 1976 (it was an HP-97).
Same, I hope the HP calculators do not expire.
The HP 50g blue is a good reason for me to buy one even I own the 50g black already - having now one at home and one at the office. Further, the keyboard of the HP 50g blue is much better readable.
CI, I like the blue keyboard better. I may be biased though since blue is my favorite color.Eddie
