In a square matrix the minor `M_(ij)` and the co-factor `A_(ij)` of and element `a_(ij)` are related by

If A=[a_(ij)] is a square matrix of order 3 and A_(ij) denote cofactor of the element a_(ij) in |A| then the value of |A| is given by

Let A=[a_(ij)]_(n xx n) be a square matrix and let c_(ij) be cofactor of a_(ij) in A. If C=[c_(ij)], then

"In a square matrix "A=a_(ij)" if i>j then "a_(ij)=0" then the Matrix A is"

Name the square matrix A = [a_(ij)] in which a_(ij) = 0, I ne J .

Let A=[a_(ij)]_(nxxn) be a square matrix and let c_(ij) be cofactor of a_(ij) in A. If C=[c_(ij)] , then

In square matrix A=(a_(ij)) if i lt j and a_(ij)=0 then A is

A square matrix A=[a_(ij)] in which a_(ij)=0 for i!=j and [a]_(ij)=k (constant) for i=j is called a

A square matrix (a_(ij)) where a_(ij)=0 for i!=j and a_(ij)=k (constant) for i=j is called

Write the element a_(12) of the matrix A=[a_(ij)]_(2xx2) , whose elements a_(ij) are given by a_(ij)=e^(2ix)sinjx .
