TI-Nspire™ CAS

L application ne s’ouvre pas correctement Gros problème de fonctionnalité

The application does what it claims. I like the calculator, but I don’t see Texas Instruments improving the application to its best. Now the IPadOS 15 is here, and iPads themselves have been improved a lot, but this application remains static and rigid, resembling a previous standard…no updates in particular Texas Instrument should consider the fact that technology nowadays is conveying the idea of being more futuristic day by day. If smartphones and iPad are reaching more people, then iPad and smartphone versions of this application should should be offered more frequently. I would say, not leaving the hand held calculators, but definitely working more on this type of software. Apple also does a terrible job approving apps lacking of some basic parameters…like an app should in principle cover or fit the size of the screen.

I absolutely love the idea of adapting the well-known Ti-Nspire CAS system for iOS. For those who know the world of computer-algebra systems Ti-Nspire is the small cousin of Mathematica or Maple systems, but imagine having a less powerful Mathematica on your Iphone, ready to be used when you’re idle on a bus. Better yet, you can really play with your hands and shift, zoom, drag graphs! You can’t really do that with Mathematica and that’s too bad. The calculator version was expensive and a pain in the neck, but now you have all the screen of your iPhone or iPad to play with. The cost ? Just don’t go to Starbucks for a week and that’s it, you paid it.

I have been using this app for several months now and I have found it to be very useful for checking answers to all sorts of pre-calculus and calculus problems. For example, entering a command similar to impDif(x^2+y^2=9,x,y) will perform implicit differentiation on the equation for a circle with a radius of 3 units.

Love the iPad app, although this comes with my school’s plan and all, this is truly an incredible app. Thank god I never had to use the real physical calculators. Anyway, good job. However, lately, after the iPad OS 13 update, this new movable keyboard was added by apple. I always use it. Unfortunately, the Npsire App recognizes it and switches its own keyboard to the tiny one and cutting all the button off in the process. I am unable to resize it within the app. This automatic keyboard transformation seems to be unintentional and just automatic because of the iPad OS 13 update. Could you please find a way to fix this. The whole keyboard gets screwed up. I am forced to exit the app, go to some other app, resize the keyboard, then come back. Obviously, just some dumb 1st world problem. But that would make your app amazing again as it was! Thank you!

There’s still no support for the ipad pro 2018

This app is amazing for calculations, creating graphs, solving systems etc... BUT it keeps crashing! It is very annoying when I'm in the middle of a complex problem and the application crashes. Please fix.

The app crashes within 2 minutes of use. Very frustrating when typing in complex long equations just to have it crash and erase my progress. This app would’ve been 5 stars if it didn’t crash. But with it crashing this often it’s a complete waste of time.

Made me fail my math test. Lame af

Crashes frequently please fix your app
