Thank you. I had been hesitating to make the purchase as I had wanted to get the apps for TI Voyage 200; but I decided to get the ones for TI-Nspire CAS CX instead, basically because it has more memory available. These apps you sell have the potential to become addictive so I most likely will be back for more! I think I made the right choice. So, needless to say, I am very impressed. Beauty is in the eye of the beholder. Your programs are my drug of choice. I am sure to enjoy them for the remainder of my life. They are one of the few things worth buying besides food and a good pair of boots.
Thank you very much! All set and working…..Great Customer Support!!!!!
Thank you very much! Chemistry Made easy for NSpire all set and working…..
Great Customer Support!!!!!
I think I’m in love with you guys

Impressed with Calculus Made Easy for Ti-Nspire
Hi Mike
I was so impressed with CME that I bought AME and PME and they are both first-rate.
I’ll be buying more as they appear.
Your apps have made the Nspire a lot more useful to me than it was – in fact, I’m beginning to like it quite a lot.
Congratulations on the hard work, I suspect your nspire apps will be even more successful than the Ti89 apps.
Best wishes
Tinspire: PQ Formel und Mitternachts (ABC) Formel
Mit dem TiNSpire kann man die PQ Formel und die Mitternachts (ABC) Formel schrittweise loesen. Mittels der TiNspire APP “Algebra Leicht Gemacht” (download https://www.tinspireapps.com/deutsch/?a=ALGLG )
Diese beiden Formeln erlauben es quadratische Gleichungen zu loesen wie etwa x2+6x+8 = 0 . Hier ist ein Beispiel mit der APP.
Zuerst waehle die Option im Menu:
Gebe die Gleichung ein und schon sieht man die Schritte unten im Fenster.
Bis die finale Loesung unten gefunden ist.
Die Mitternachtsformel kann man auf die gleiche Weise loesen:
Eingabe der Gleichung wie unten gezeigt und die Loesung ist unten
So einfach ist Algebra 😉
Tinspire: Friedmann and other Nonparametric Tests – Step by Step
Performing Nonparametric Statistics Test can easily be performed – step by step – using the TiNspire CX calculator. Check out tests such as Wilcoxon, Wallis-Kruskal and the signed Rank Test at https://tinspireapps.com/blog/perform-non-parametric-tests-such-wilcoxon-kruskal-or-signed-rank-on-the-ti-nspire/
Another example is the Friedmann Test, we will use the data of a wine test at https://www.real-statistics.com/anova-repeated-measures/friedman-test/
Ho: No wine preference vs Ha: some wine preference (white, red or rose) . Ranking the wine taste results as shown below we obtain a Test Statistic of 1.79 which results in a p-value of 0.408267 indicating no significant wine preference.
Here is the same Friedmann Test performed using the TiNspire’s Statistics Made Easy app at https://www.TiNspireapps.com/?a=SPME . First we enter the wine taste data as 3 rows, the ranks are shown to the right accounting for ties as well.
Next , we compute the sum of ranks and their averages.
Now, squaring the ranks and adding them yields 1749.5. The Test Statistics uses that, the number of tasters and the number wines and comes out to be 1.79167
Using the Chi Squared Distribution yields the p-value of 0.40827 which is not below 5% and we thus fail to reject our above stated Null-Hypotheses Ho :
