Hallo Zusammen!

Ich wüsste gerne Schritt für Schritt wie ich eine Determinante in Excel 07 berechnen kann.

Die Aufhabe lautet wie folgt:

Berechnen Sie unter Excel die Determinante von

A=
4 5
3 -2

Anmerkung:

det A=
|a b|
|c d | = a* d-b*c


Nutzen Sie hierfür die entsprechende Matrixfunktion.

Wie ist die Formel für:

A= (d/2)² mal pi

Annahme: Der Wert d steht in Zelle A6



Wurzel von 144 müsste -> = wurzel(144) sein?
Sinus 45--> = sin(45) ?
