We know that 6I2=6(1001)=(6006) So, we set the resulting matrix equal to6I2: (a+b−2a+4bc+d−2c+4d)=(6006) This gives us the following equations: 1.a+b=6 2.−2a+4b=0 3.c+d=0 4.−2c+4d=6 Step 4: Solve the equations foraandb ...
Find non-zero vectors {eq}\vec{x} {/eq} and {eq}\vec{y} {/eq} that are both orthogonal to $$\begin{bmatrix} 1\\ 1 \\ 1 \end{bmatrix} $$ and orthogonal to each other. Orthogonal Vectors: We say that 2 vectors are ...

How to Find the Inverse of a 2x2 Matrix: Example 3 (Using Row Operations and the Previous Example) Find the inverse of the following matrix, if it exists. A=[2−135] Step 1: Check that the determinant is not zero.det(A)=det([2−135])=(2)(5)−(3)(−1)=10+3=13 ...
x+y+2==-x=2x+y+2==02 (1) Equating the middle elements, 4x+2y-3==-y=4.x+3y-3==0 (2) Equating the bottom elements, 4x+2y+3==-==4x+2y+4==0 (3) (2)-(3) gives y-7==0 Setting = = 1 gives y = 7 and x = -2 -9 A corresponding eigenvector is 14 2 1=3: ...
(n and m do not exceed 20). A two-dimensional matrix stores the information on the sold tickets, number 1 means that the ticket for this place is already sold, the number 0 means that the place is available. You want to buy k tickets to the neighboring seats in the same row. Find...
so we have six matrixs that must not be zero . every matrix is composed by the two vector (x1,x2,x3,x4,x5,x6) and (y1,y2,y3,y4,y5,y6) and 4 vectors among the eight vectors of H1, H2 H3 and H4. for example A1 = [1 0 0 0 x1 y1;0 1 0 0...
