POLL: What would you like to see in a new Function/Equation Library?

[acmeanvil]

I wanted to take a poll of what people would find useful and practical to have in a menu driven function/equation library for the Prime, with an emphasis on solving ahead of equation display.

1) I think the HP50g library is a great baseline (for those who actually have used it on a 50g), but I would be curious to know what people actually use, or have created themselves because they needed something more specific or different than was available.

2) For those who have no idea about the equation library from the 50g, same question, what do/would you actually use, or you would create that would be helpful day to day.

3) Or less specific, what subject area of functions would be helpful? (ie Mechanical Engineering categories: statics, dynamics, heat transfers, fluid flow, etc.). Electrical Eng., Structural Eng., Physics, Machining, Basket weaving, you name it.
