Now, we need to calculate the determinant of the matrix A−λI: det(A−λI)=(cosθ−λ)(cosθ−λ)−(−sinθ)(sinθ) This simplifies to: det(A−λI)=(cosθ−λ)2+sin2θ Step 3: Set the determinant to zeroNow, we set the determinant equal to zero to find the...
Since A is a 3×3 matrix, n=3. Thus,|adj(A)|=|A|3−1=|A|2=12=1 Step 3: Calculate the Determinant of the Adjoint of the AdjointNow, we need to find |adj(adjA)|. Using the same property again:|adj(adjA)|=|adj(A)|n−1Substituting the value we found:|adj(adjA)|=...
