Applications … Non commutativity of multiplication of matrices and existence of non-zero matrices whose product is the zero matrix (restrict to square matrices of order 2). (ii) Determinants . Continuity and Differentiability 2. Product of two non-zero numbers is always non-zero).But product of two non-zero matrices can be zero matrix. proof of the uniqueness of inverse, if it exists. Noncommutativity of multiplication of matrices and existence of non-zero matrices whose product is the zero matrix (restrict to square matrices of order 2).Concept of elementary row and column operations. If a square matrix has all elements 0 and each diagonal elements are non-zero, it is called identity matrix and denoted by I. The mortal matrix problem is the problem of determining, given a finite set of n × n matrices with integer entries, whether they can be multiplied in some order, possibly with repetition, to yield the zero matrix. We prove that if A is a nonsingular matrix, then there exists a nonzero matrix B such that the product AB is the zero matrix. Concept of elementary row and column operations. Matrices 2. i.e. Determinants – Existence of non-zero matrices whose product is the zero matrix – Concept of elementary row and column operations – Proof of the uniqueness of inverse, if it exists : Unit – 3: Calculus 1. matrices, zero and identity matrix, transpose of a matrix, symmetric and skew symmetric matrices. and existence of non-zero matrices whose product is the zero matrix (restrict to square matrices of order upto 3). 1.Matrices existence of non-zero matrices whose product is the zero matrix. Occurrences. Answer. Invertible matrices and proof of the uniqueness of inverse, if it exists; (Here all matrices will have real entries). The zero matrix is the only matrix whose rank is 0. "Using an example show that product of two non-zero matrices is a zero matrix." 2.Determinants properties of determinants Consistency, inconsistency and number of solutions of system of linear equations by examples, Unit-III: Calculus Noncommutativity of multiplication of matrices and existence of non-zero matrices whose product is the zero matrix (restrict to square matrices of order 2).Concept of elementary row and column operations.
