If there is a problem with the HP Prime, it is the lack of software available for it for the different professional fields: finance, engineering, physics, etc. The calculator, while extremely powerful, and programmable in a much more user-friendly language than the elegant but complicated RPL, was intended for secondary education, with extension to university maths, due to its extensive CAS system. However, if you wanted to load a formula for any physics or engineering problem, you were out of luck - they had not been programmed before.
I have tried to put together some account sets in the solver app - but I am limited to 10 for each app I set for it; and the selection of functions, and its use, could be clearly improved.
I am now excited, since I have seen exactly what I was looking for. Eddie B. Shore has created an equation library with 47 different equations that can be loaded in the solver app, covering many categories:
I am now traveling, but I really look forward to get into my computer and load it in my Prime!
