I have got an older (2006) NSpire CAS with OS 3.2 which I rarely use other than for working out integrals/differentials when I get stuck with pen and paper.
TBH the Nspire CAS is large, clunky, complicated, unintuitive, eats batteries and is not a whole lot faster or more functional than a TI89.
I still however, use a TI86 all the time out of choice as the stat graphing is great (I mainly use it for regression analysis), it does base-N very well, has conversions built in, has a good solver and the programming language is simple enough to fit in my head.
I have a fairly large set of programs I've developed for the TI86 as well for dealing with navigation/triangulation/mapping.
- fusiongyro 14y agoThe Nspire CAS is really more of a tool for students. I'd call the point-and-click interface clunky and intuitive--it's not hard to figure out how to do things, it's just going to take you a while to get there. :) I'd imagine if you have software you've written for the TI-86 and are inclined to do integrals and differentials on paper until you get stuck, it's probably not the right tool for you. :)
- eckyptang 14y agoI agree with you there about the student comment! I do find it poorly integrated though, for example: To do a linreg on some data and project that past the extents of the dataset requires... NSpire: create document, create spreadsheet, enter data, create stats plot, analyse->regression->linreg, create graph, plot stat func, set zoom constraints, whack X value in, read Y. That's just shit, student or not. TI-86: {1,2,3,4}->xStat, {3,6,8,10}->yStat, catalog->LinReg, Graph, zoom, enter X, done. Probably right about it not being the right tool. Anyone want to buy an NSpire CAS? £30 including delivery to the UK :)
