Notation scientifique sur la TI NSPIRE

Soumis par Laurent Petit cours le mar, 10/02/2015 - 16:58

 

Par défaut la TI NSPIRE affiche les "résultats du classeur" avec les réglages suivants

Afficher chiffres: flottant 6

Format exponentiel: Normal

Mode de calcul: Auto

Ce qui a pour effet de laisser généralement les résultats sous forme exacte.

 

Comment passer en notation scientifique?

Il faut modifier les résultats en cliquant en bas de page d'accueil sur "Réglages"

 

Puis sur 2 "Réglages du classeur"

Par défaut on obtient l'écran suivant

On modifie le Format exponentiel  de Normal à Scientifique

On modifie Mode de calcul de Auto à Approché

 

On obtient alors l'écran

 

Puis avec la touche Tab en haut à gauche du clavier

après plusieurs clics la zone de l'écran "Par défaut " s'entoure de bleu

on clique alors avec le centre du Pad puis une deuxième fois sur OK

C'est fait: le Scratchad est en mode notation scientifique. Ce qui est la notation utile en physique.

 

Quand on revient aux mathématiques il est préférable de revenir au calcul exact.

 

Il suffit de rentrer dans les réglages puis avec la touche  "tab" de se déplacer sur  "Restaurer" puis on valide deux fois en cliquant sur le centre du Pad.

 

On est revenu au réglage initial.
