Answer:
symmetric matrix is the square matrix and it is equal to its transpose
Step-by-step explanation:
solution
a symmetric matrix is the square matrix and it is equal to its transpose
As A is symmetric matrix then
A = 
here only square matrices will be symmetric
and matrix A is symmetric its mean its matrices have equal dimension
and every square diagonal matrix is also symmetric when all off diagonals element is zero
symmetric matrix for all indices i and j
A = aij = aji
Answer: No, because an identity is an equation that is always true and cos(theta) - sin(theta) does not always equal 1.
Hope this helped! :)
