Calculs de proportionnalité
Utilisez le mode PROP ( [ MODE ] 6 ( PROP ) ) pour les calculs de
proportionnalité.
Ce mode permet de calculer la valeur de X dans la relation de
proportionnalité a:b=X:d (ou a:b=c:X) pour des valeurs de a, b, c et d
connues. (Voir exemple 54)
Pour résoudre cette relation par rapport à X
1. Pressez [ MODE ] [ 6 ] [ 1 ] ou [ MODE ] [ 6 ] [ 2 ].
2. Entrez la valeur des coefficients a, b, c, d et pressez [ = ]. Appuyer
sur [ AC ] pour effacer toures les valeurs entrées.
3. Pressez [ = ] pour trouver la valeur de X.
4. Pressez [ = ] ou [ AC ] pour retourner à l’écran de choix des
coefficients.
(Note) : 1. Après avoir entré une valeur de coefficient, appuyer
sur [ = ]. La valeur entrée s’affiche alors dans la cellule
avec une précision de 6 digits.
2. Vous ne pouvez transformer la valeur de votre résultat
en notation ingénieur lorsque la solution est affichée à
l’écran.
3. Le message d’erreur Math ERROR apparait si vous
entrez la valeur 0 pour un des coefficients.
