WebThe determinant will be equal to the product of that element and its cofactor. In this case, the cofactor is a 3x3 determinant which is calculated with its specific formula. Example 33 $\begin{vmatrix} 1 & 3 & 9 & 2\\ 5 & 8 & 4 & 3\\ 0 & 0 & 0 & 0\\ 2 & 3 & 1 & 8 \end{vmatrix}$ We notice that all elements on row 3 are 0, so the determinant is 0. WebDeterminants for Class 12 notes are available here, as per the syllabus guided by the boards. We have already learned that the algebraic equations can be expressed in the form of matrices. To determine the uniqueness of solution associated with such matrices, we find the determinant. It has huge applications in Engineering, Economics, Science, etc.
