„Grundlegende arithmetische Berechnungen für Basen

zSie können mit dem Taschenrechner in anderen Basen als der des Zehnersystems rechnen. Sie können binäre, oktale und

hexadezimale Zahlen addieren, subtrahieren, multiplizieren und dividieren. Vgl. Beispiel 61.

„Logische Berechnungen

Logische Berechnungen können durch logische Produkte (AND), negative logische Berechnungen (NAND), logische Summen (OR), exklusive logische Summen (XOR), Negationen (NOT), und die Negation exklusiv logischer Summen erfolgen (XNOR). Vgl.

Beispiel 62.

Mode 3 - CPLX

zDer Mode für komplexe Zahlen (CPLX) erlaubt eine Addition, Subtraktion, Muotiplikation und Division komplexer Zahlen. Vgl. Beispiel 63. Das Ergebnis einer Rechenoperation mit komplexen Zahlen kann wie folgt dargestellt warden :

Re

Realwert

Im

Imaginärer Wert

ab

Absoluter Wert

ar

Argument-Wert

Mode 4 - VLE

Der Mode für variable lineare Gleichungen (VLE) erlaubt die Berechnung eines Sets von simultanen Größen mit zwei Unbekannten wie folgt :

a x + b y = c

d x + e y = f, dabei sind x und y unbekannt.

zIm Mode VLE geben Sie einfach die Koeffizienten ( a, b, c, d, e, f ) in der richtigen Reihenfolge ein. Der Taschenrechner berechnet dann automatisch die Werte für x und y. Vgl. Beispiel 64.

Mode 5 - QE

Der Mode für quadratische Gleichungen (QE) kann folgende Rechenoperationen lösen :

a x 2 + b x + c = 0, wobei x unbekannt sind.

zIm Mode QE geben Sie einfach die Koeffizienten ( a, b, c ) in der richtigen Reihenfolge ein. Der Taschenrechner berechnet automatisch die Werte für x. Vgl. Beispiel 65.
