4. Cofactor C22: C22=(−1)2+2⋅det[1]=1⋅1=1 Step 2: Form the Cofactor Matrix Now we can form the cofactor matrix C:C=[C11C12C21C22]=[4−3−21] Step 3: Transpose the Cofactor Matrix To find the adjoint, we need to take the transpose of the cofactor matrix:adj(A)=...
Now, the cofactor matrix is: Cofactor Matrix=⎡⎢⎣7−1−1−310−30−1⎤⎥⎦ Taking the transpose gives us the adjoint: adj(A)=⎡⎢⎣7−3−3−110−10−1⎤⎥⎦ Step 3: Calculate the Inverse of A The inverse of A is given by: A−1=1det(A)...
