Visualize crucial connections by observing how equations change - in real time, on one screen - when you touch, grab and interact with shapes, graphs and objects on the screen. Make math more meaningful by importing images from the iPad camera or photo library and overlaying graphs and equations on them to illustrate abstract math principles in the real world.* Solve equations with algebraic precision, factor and expand variable expressions, complete the square, find antiderivatives, compute limits, find exact solutions in irrational form and more. Open the door to math mastery with the first-in-class iPad CAS app that delivers comprehensive graphing, data entry and analysis, statistical modeling and calculating functionality.
1 recommended brand of graphing calculators in the U.S., has optimized its most powerful Computer Algebra System (CAS) math engine for an all-in-one iPad app that makes teaching and learning math more engaging, meaningful and … fun! Nowadays, new releases of ASM programs on the Nspire series are very infrequent, and there are few developers.īTW: if your research led you to eliminating the powerful HP Prime, despite its superior CAS and raw CPU power, why ? The fact that basically nobody is interested enough in low-level programming on the Prime ?įrankly, if you really want to go into low-level development, for learning purposes, there are lots of platforms more useful and cheaper than any calculator, with larger development communities.Texas Instruments, the No. While a closed platform on which TI keeps fighting the community, the Nspire CX CAS has more raw CPU power and a slightly better CAS, derived from that of the 89T. IOW, the 89T is more than 10 years past its sweet spot, and while I still like that platform, on and for which I worked a lot, I have a hard time recommending the 89T as a new purchase. There's been hardly any new TI-68k development activity for years, and that wasn't because of the Nspire series. the 89T became available in 2004, the last OS update for the 89T was released in 2005, and the community of programmers belittled a lot in 2006-2007, without ever recovering. At the time, exam testing mode wasn't a thing, and TI wasn't afraid of people tampering with it and therefore wasn't trying (and repeatedly failing) to lock the calculator down. * quite good ASM / C programming: unlike the Nspire series, which is succeeding it, the TI-68k series (to which the 89T belongs) is an open platform, with direct access to assembly, and a good community toolchain (nowadays, GCC4TI).
* decent TI-Basic programming, whose abilities can be expanded (and speed can be improved) through ASM programs
