If A is a square matrix of order n, then the determinant of its adjoint matrix, |adj(A)|, is equal to:

If A is a non-singular 3 × 3 matrix and det(ATA) = 16, then det(A) is equal to:

If the minimum and the maximum values of the function f: [π/4, π/2] → R, defined by the determinant of the matrix given below are m and M respectively, then the ordered pair (m, M) is equal to: f(θ) = det -sin2θ-1-sin2θ1-cos2θ-1-cos2θ11210-2
