Bab 2 Vektor, matriks, dan kombinasi linear
Kita memulai kajian tentang sistem linear dalam
Bab 1 dengan menyatakan sistem linear melalui matriks diperbesar, seperti
\begin{equation*}
\left[
\begin{array}{rrr|r}
1 \amp 2 \amp -1 \amp 3 \\
-3 \amp 3 \amp -1 \amp 2 \\
2 \amp 3 \amp 2 \amp -1 \\
\end{array}
\right]
\end{equation*}
Pada bab ini, kita akan menyingkap informasi geometris di dalam matriks seperti ini. Informasi tersebut akan membawa kita pada pemahaman intuitif atas wawasan yang sebelumnya kita peroleh mengenai solusi sistem linear.
