I think the equation library is meant mostly for engineers rather than mathematicians. That's why you see things like moments of inertia.

I don't have the 50 either but I suspect it has the same library as the 48. I trust someone will correct me if I'm wrong.

That is essentially correct. On a related topic, I wanted to ask someone more familliar with the 50g than I am (I still do not own one. The price and availability seem to have me hexed.) if the Library contains anything for astrophysics and astrodynamics, beyond the simple standards usually lumped in with physics on some other popular handhelds?
If such a library is found lacking, I should like to put forth some effort to creating a library whose primary application would be the application of Kepler and other standards to the study of satellite motion and the prediction of windows of observation, through the use of standard two-line element (TLE) sets.
Obviously, one does not wish to re-invent the wheel. I have a considerable body of experience brought over from use of the 48gx for the same applications. Such a library may already exist. If so, the only question remaining would be conversion and compilation/ importation from the 48gx to the 50g.

Any thoughts along this line of country would be appreciated, and I would, naturally, make any such library or application freely available to all for use.

     Hi Roci... Hi Don:

 

     No, the HP-50g doesn't have any library for astrophysics nor astrodynamics. Here in this group are the 3 manuals (beginner, medium and advanced) for this great HP calculator; you can download them freely and check by yourself for the 15 subjects of the Equation Library.

 

     Of course, Roci, it will be a big big thing if you can provide us with such Astronomical Equation Library.

 

     I don't know where you are, Roci, but here in Mexico a new from store HP-50g is not so expensive; you can buy it for 146 USD (1,850 MXN).

 

     Have a good day...

 

 

     Ceolintzin.
