- Isn't it nuts to carry around a HP95 and a calculator?
-
- I would say that the most useful functions for me would be:
-
- -Unit Conversions
- -Fundamental Constants
- -2D graphing
- -Could handle complex numbers.
-
- -It would be helpful if the calculator could multiply out vectors
- and matrices. Take inverses of matrices as well as finding
- eigenvectors and values.
-
- -A way to input and output fractions would be useful
-
- -Like the constants, a place to store the most used functions like:
- -Bessel Fns
- -Legendre Polynomials
- -Spherical Harmonics
- -Hermite/Laguerre/Chebyshev...
- -etc.
- -Distributions
- -Gaussian
- -Poisson
- -Maxwell-Boltzmann
- -Fermi/Dirac
- -Bose/Einstein
- I wouldn't do anything fancy with them, but have them stored so that
- they could be graphed, or so I could get the value of BesselJ[n,Pi]
- (Can you tell that I use Mathematica?) I guess if there was a way to
- store complicated polynomial expressions and just be able to evaluate
- them would be useful.
- Actually, using Mathematica input commands/formats could be good for
- being able to port expressions to that program.
-
- Just a couple of ideas.
