Formulas

Determinant formula for a 2x2 matrix: det(A) = ad - bc
Inverse formula for a 2x2 matrix: A^(-1) = (1/det(A)) * adj(A)
Matrix multiplication rule: (AB)_{ij} = Σ A_{ik} B_{kj}

Theorems

Inverse of a matrix theorem: A * A^(-1) = I
Matrix determinant properties: det(AB) = det(A) * det(B)
Solution of matrix equations using inverse: X * A = B => X = B * A^(-1)
