WebUsing the definition of a determinant you can see that the determinant of a rotation matrix is cos 2 ( θ) + sin 2 ( θ) which equals 1. A geometric interpretation would be that the area does not change, this is clear because the matrix is merely rotating the picture and not distorting it in any other way. Share Cite Follow WebAug 31, 2024 · The determinant is the product of the zeroes of the characteristic polynomial (counting with their multiplicity), and the trace is their sum, regardless of diagonalizability of the matrix. If the underlying field is algebraically closed (such as C ), then those zeroes will exactly be the eigenvalues. Proof: WebThe Leibniz formula for the determinant of an n × n matrix A is det(A)= ∑ σ∈Sn(sgn(σ) n ∏ i=1ai,σ), det ( A) = ∑ σ ∈ S n ( sgn ( σ) ∏ i = 1 n a i, σ i), where sgn is the sign function of permutations in the permutation group Sn, which returns +1 and −1 for even and odd permutations, respectively. can low blood pressure cause hallucinations
