Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations. As shown by Cramer’s rule, a nonhomogeneous system of linear equations has a unique solution if the determinant of the system’s matrix is nonzero (i.e., the matrix is nonsingular). Know More about these in Determinants Class 12 Notes List.
