Anyone using anything fancy like this TI-nSpireCX-CAS?
I was given this about 3 years ago and it's been sitting in a drawer since then. Today I finally decided to open the package and take it out and see what exactly it can do... well, it's way, way beyond my needs and just about everything I've seen on the 'web makes it out to be more for school/student use than for real world use.
After playing around with it I realized my old eyes really needed a calculator with a back-lit color screen!
So, what can this do? Well I found quite by accident that it can convert fractions to and from decimal...
But, there has to be more to this thing...I found a very nice program that runs on it called "EEPro" that's for electric calculations...
However after much searching I haven't found any programs with with Feet-Inches-fractions, conversion to metric and back, etc. I have an HP-50G that has an add-on program that can do feet-inches-fractions and it would seem that *someone* *somewhere* would have done the same for the TI-nSpire, but if it exists I haven't been able to find it.
This calculator is probably overkill for my needs, but I intend to use it just because the back-lit screen makes it so much easier to read. I already have a couple of Foot-Inch calculator models; one's an architectural version that does stairs and roofs among other things and one suited more for contractors that estimates quantities like bricks and studs, etc. So it's not like I'm without that ability, but I'd like to consolidate everything into one calculator if possible.
