If matrix `A=[[1, -1], [1, 1]]` then

If matrix A=[[1,-1],[-1 ,1]] and A^2=k A , then write the value of k

If matrix A=[[1,-1],[-1 ,1]] and A^2=k A , then write the value of k

If the matrix A=((1,-1),(-1,1)) then A^(n+1)=

If matrix A=[[1,-1-1,1]] and A^(2)=kA then write the value of k and A^(2)=kA

(i) Show that the matrix A=[[1,-1, 5],[-1, 2, 1],[ 5, 1, 3]] is a symmetric matrix. (ii) Show that the matrix A=[[0, 1,-1],[-1, 2, 1],[ 1,-1, 0]] is a skew symmetric matrix.

If matrix A=[(1,-1),(-1,1)] and A^2=kA then write the value of k.

If matrix A = {:[(1,-1),(-1,1)] and A^2 = kA , then write the value of 'k'.

If the matrix A=[(1,-1),(-1,1)] and A^(2)=kA ,then write the value of k
