Vedclass · Answer

(B) ધારો કે $A = \begin{bmatrix} 1 & 2 & 3 \ 0 & 1 & 2 \ 0 & 0 & 1 \end{bmatrix}$.પ્રથમ,આપણે નિશ્ચાયક $|A| = 1(1 	imes 1 - 2 	imes 0) - 2(0 	imes 1 - 2 	imes 0) + 3(0 	imes 0 - 1 	imes 0) = 1(1) = 1$ ગણીએ છીએ.કારણ કે $|A| 
eq 0$,તેથી વ્યસ્ત શ્રેણિક $A^{-1}$ અસ્તિત્વ ધરાવે છે.આગળ,આપણે સહઅવયવ શ્રેણિક $C_{ij}$ શોધીએ છીએ:$C_{11} = +|\begin{smallmatrix} 1 & 2 \ 0 & 1 \end{smallmatrix}| = 1, C_{12} = -|\begin{smallmatrix} 0 & 2 \ 0 & 1 \end{smallmatrix}| = 0, C_{13} = +|\begin{smallmatrix} 0 & 1 \ 0 & 0 \end{smallmatrix}| = 0$$C_{21} = -|\begin{smallmatrix} 2 & 3 \ 0 & 1 \end{smallmatrix}| = -2, C_{22} = +|\begin{smallmatrix} 1 & 3 \ 0 & 1 \end{smallmatrix}| = 1, C_{23} = -|\begin{smallmatrix} 1 & 2 \ 0 & 0 \end{smallmatrix}| = 0$$C_{31} = +|\begin{smallmatrix} 2 & 3 \ 1 & 2 \end{smallmatrix}| = 4-3 = 1, C_{32} = -|\begin{smallmatrix} 1 & 3 \ 0 & 2 \end{smallmatrix}| = -2, C_{33} = +|\begin{smallmatrix} 1 & 2 \ 0 & 1 \end{smallmatrix}| = 1$આમ,$Adj(A) = \begin{bmatrix} 1 & -2 & 1 \ 0 & 1 & -2 \ 0 & 0 & 1 \end{bmatrix}$.અંતે,$A^{-1} = \frac{1}{|A|} Adj(A) = \frac{1}{1} \begin{bmatrix} 1 & -2 & 1 \ 0 & 1 & -2 \ 0 & 0 & 1 \end{bmatrix} = \begin{bmatrix} 1 & -2 & 1 \ 0 & 1 & -2 \ 0 & 0 & 1 \end{bmatrix}$.

$\begin{bmatrix} 1 & 2 & 3 \\ 0 & 1 & 2 \\ 0 & 0 & 1 \end{bmatrix}$ નો વ્યસ્ત શ્રેણિક શોધો.
