Hausaufgabe 23: (Inverse einer Matrix) a) Berechnen Sie die Inverse der Matrix \[ A=\left(\begin{array}{ccc}0 & -3 & -2 \\ 1 & -4 & -2 \\ -3 & 4 & 1\end{array}\right), \] indem Sie die Matrix \( A^{-1} \) in allgemeiner Form ansetzen und ihre unbekannten Matrix- elemente über die Forderung \( A A^{-1}=\mathbf{1}_{3} \) ermitteln. b) Prüfen Sie Ihr Ergebnis aus a), indem Sie das Matrixprodukt \( A A^{-1} \) ausführen. (Die Be- rechnungen der Einträge in der 1. Spalte von \( A A^{-1} \) sind dabei detailliert aufzuschreiben.)

1. At the beginning of this task, you were asked to make predictions about the science behind various phenomena. For each of the following phenomenon explain why they happen. Cite evidence from stations in task 1 to support your answer. - Day and night - Seasons (fall, winter, spring, summer) - Phases of the moon - Night sky changes throughout the year - Eclipses 2. In this task, we focused on the crosscutting concepts of: - Patterns: Graphs, charts, and images can be used to identify patterns in data. What activities did we do that used patterns? What did we learn from these activities?
