$$$\left[\begin{array}{cc}3 & 2 t\\0 & 2\end{array}\right]$$$'nin determinantı

Hesaplayın $$$\left|\begin{array}{cc}3 & 2 t\\0 & 2\end{array}\right|$$$.

2x2 boyutlu bir matrisin determinantı $$$\left|\begin{array}{cc}a & b\\c & d\end{array}\right| = a d - b c$$$ olarak verilir.

$$$\left|\begin{array}{cc}3 & 2 t\\0 & 2\end{array}\right| = \left(3\right)\cdot \left(2\right) - \left(2 t\right)\cdot \left(0\right) = 6$$$

$$$\left|\begin{array}{cc}3 & 2 t\\0 & 2\end{array}\right| = 6$$$A
