Jika kalkulator tidak menghitung sesuatu atau Anda menemukan kesalahan, atau Anda memiliki saran/masukan, silakan hubungi kami.

Masukan Anda

Hitung $$$\left|\begin{array}{cc}- 2 \sin{\left(2 t \right)} & 1\\- 4 \cos{\left(2 t \right)} & 0\end{array}\right|$$$.

Solusi

Determinan matriks 2x2 adalah $$$\left|\begin{array}{cc}a & b\\c & d\end{array}\right| = a d - b c$$$.

$$$\left|\begin{array}{cc}- 2 \sin{\left(2 t \right)} & 1\\- 4 \cos{\left(2 t \right)} & 0\end{array}\right| = \left(- 2 \sin{\left(2 t \right)}\right)\cdot \left(0\right) - \left(1\right)\cdot \left(- 4 \cos{\left(2 t \right)}\right) = 4 \cos{\left(2 t \right)}$$$

Jawaban

$$$\left|\begin{array}{cc}- 2 \sin{\left(2 t \right)} & 1\\- 4 \cos{\left(2 t \right)} & 0\end{array}\right| = 4 \cos{\left(2 t \right)}$$$A
