== Composition d'un moteur CAS ==
Un '''CAS''' ou ''Computer Algebra System'' est une fonctionnalité avancée de calcul proposée par des programmes informatiques.


Sur les calculatrices [[Texas Instruments]], plusieurs modèles possèdent des OS avec CAS, et dans le cas des [[TI-Nspire]] la présence d'un moteur CAS est même précisée dans le nom du modèle: TI-Nspire CAS, TI-Nspire CX CAS, etc...


== Composants d'un moteur CAS ==
Un moteur CAS se compose de 5 piliers ou briques essentielles:


; 1) Un système prenant en compte la priorité des opérations
: Cela parait stupide, mais il c'est la base de tout moteur CAS: savoir dans quel ordre il devra simplifier son expression pour calculer ensuite.

; 2) Un moteur permettant de travailler sur des formes exactes ''(fractions, radicaux...)''
: Aussi appelé '''Calcul exact''', cette fonctionnalité permet d'obtenir des résultats non approximatifs, mais en valeur réelle.

; 3) Un moteur permettant de travailleur sur des formes symboliques
: Aussi appelé '''Calcul symbolique''', il s'agit ici d'être capable de calculer des choses non plus avec des nombres mais avec des lettres. Ce moteur est à la base de la factorisation d'expressions, développement, identités remarquables, etc... Le moteur doit avoir compris que la lettre représente une valeur inconnue.

; 4) Un moteur permettant de saisir une expression en écriture naturelle
: TI appelle ce principe le [[MathPrint]] où parfois [[PrettyPrint]]. Il s'agit ici de permettre à l'utilisateur d'entrer ses calculs dans une notation qui est la même que celle des livres de maths, avec des nombres ou expressions en exposant placées en haut, des fractions à étages, des racines recouvrant les expressions, des intégrales et des sommes avec leurs bornes dessous et dessus, etc... Et pas seulement avec des fonctions suivies d'arguments.

; 5) Un moteur permettant d'afficher le résultat en écriture naturelle
: Cette fois aussi, le résultat affiché doit être affiché comme dans les livres. A noter que la saisie et l'affichage du résultat en écriture naturelle sont deux briques très différentes au niveau routines à programmer.
$$
  \sum f(x) = F(x) + g(x)
$$

=== Fonctionnalités ===
On attribue ensuite aux moteurs CAS des fonctionnalités avancées, telles que la résolutions d'équations complexes, la dérivation ou l'intégration de formules.


Ces fonctionnalités sont permises par les 5 briques évoquées précédemment, qui rendent ces calculs possibles.
Ensuite, les moteurs CAS plus avancés peuvent posséder des fonctionnalités graphiques (graphes de courbes à plusieurs variables (3D), dessins vectoriels, etc...)

These computer algebra systems are sometimes combined with "front end" programs that provide a nice user interface, such as the general-purpose [[GNU TeXmacs]].
