Determinants and Matrices - BYJU
WebThe NCERT Solutions Class 12 of BYJU’S for Chapter 4 cover the following points and formulas. If any two rows or any two columns are identical or proportional, then the value of the determinant is zero. A square matrix A has an inverse if and only if A is non-singular. The unique solution of equation AX = B is given by X = A–1 B, where A ≠ 0. WebRevision Notes on Matrices & Determinants. Two matrices are said to be equal if they have the same order and each element of one is equal to the corresponding element of the other. An m x n matrix A is said to be a square matrix if m = n i.e. number of rows = number of columns. In a square matrix the diagonal from left hand side upper corner to ... phil-iri form 3b
