Inverse of a 3×3 matrix by cofactor expansion

In this video, we learn how to find the inverse of a 3×3 matrix using the Cofactor Expansion method in a clear and easy step-by-step process. Cofactor expansion is one of the most important techniques in Linear Algebra. We first calculate the determinant using cofactor expansion, then find the matrix of cofactors, form the adjugate (adjoint) matrix, and finally compute the inverse. • How to find the determinant of a 3×3 matrix using cofactor expansion • How to compute cofactors correctly • How to form the adjugate matrix • How to calculate the inverse step-by-step This tutorial is perfect for school students, college students, engineering students, and anyone preparing for exams who wants a strong understanding of matrix inverses.
