Bonjour, J'aimerais avoir votre avis. Quelle serait la raison (ou les raisons) de remplacer une TI-Nspire CX CAS par la nouvelle TI-Nspire CX II-T CAS ? J'ai vu graphiques dans le basic, et légère augmentation de la vitesse. Si j'ai bien lu. Mais ce n'est probablement pas tout. L'inconvénient est c...

You're welcome, mate

What is the temperature coefficient (Alpha) of Ni ?
Given Alpha=2.7*10^(-4) °C^(-1), we have R(T final)=115 Ohm, from which R0=115/(1+2.7*10^(-4)*55)=113.3 Ohm.
So we will have 2*(113.3+Rs)=230 (Rs is the series resistance), from which Rs=1.7 Ohm.
Happy August holidays,

It's a pleasure
Have a nice week-end !

CAS (computer algebra system) calculators can solve equations, factor, manipulate variables and so forth. The CX II Handheld includes a faster processor, a new software versione (5.0) and some additional features to improve usability. Probably the Nspire CX CAS will no longer supported. Best, Hisham...

Sure

Bonjour, j’ai des devoirs à faire pour ma rentrée en 1ère, je bloque sur une des questions qui est « À l’aide de la calculatrice, déterminer les antécédents par g de 2/3 » donc je définis ma fonction g sur ma calculatrice : g(x):=(-5)/(2(x*x)-3) et ensuite je tape : solve(g(x)=2/3,x) et ma calculat...

This can be done simply through the basic functions of the calc, there is no need of such a program
If you have to, you can just write a simple app (using TI-Basic) on your own.
Best,

Hisham

I can't see anything so far, sorry

Just solve the system of the two circles equations (as an alternative you can solve graphically)
One solution indicates two circles touch each other (internally or externally), two solutions indicate they intersect in two points, zero solutions indicate they don't intersect.
