Formulas

Determinant of a 3x3 matrix: det(A) = a(ei − fh) − b(di − fg) + c(dh − eg)
Inverse of a matrix: A^-1 = 1/det(A) * adjugate(A)
Cofactor matrix: Matrix of signed minors of A

Theorems

A matrix is invertible if and only if its determinant is non-zero.
The adjugate of a matrix is the transpose of its cofactor matrix.
