Übung: Determinante einer 3×3 Matrix

makeMatrix(randRange(-2, 5, DIM, DIM)) matrixDet(MAT) "\\textbf " + randFromArray("ABCDEF")

PRETTY_MAT_ID = printSimpleMatrix(MAT)

Was ist die Determinante von PRETTY_MAT_ID?

SOLN
3 makeMatrix([["a","b","c"],["d","e","f"],["g","h","i"]])

Die Determinante einer 2×2 Matrix kann wie folgt mit der Regel des Sarrus berechnet werden:

printSimpleMatrixDet(HINT_MAT) = matrix3x3DetHint(HINT_MAT, true)

= matrix3x3DetHint(HINT_MAT)

In diesem Fall bedeutet dies, dass

printSimpleMatrixDet(MAT) = matrix3x3DetHint(MAT, true)

= matrix3x3DetHint(MAT)

= SOLN
