question_answer1) Directions : (1 - 7) The following questions consist of two statements, one labelled as "Assertion [A] and the other labelled as Reason [R]". You are to examine these two statements carefully and decide if Assertion [A] and Reason [R] are individually true and if so, whether the Reason [R] is the correct explanation for the given Assertion [A]. Select your answer from following options. Assertion [A]: is an identity matrix. Reason [R]: A matrix \[A=\left[ {{a}_{ij}} \right]\] is an identity matrix if .
question_answer2) Assertion [A]:Matrix is a column matrix. Reason [R]: A matrix of order \[m\times 1\] is called a column matrix.
question_answer3) Assertion [A]:Transpose of the matrix \[A=\left[ 2\,\,5\,\,-1 \right]\], is column matrix. Reason [R]: Transpose of a matrix of order \[m\times n\] is a matrix of same order.
question_answer4) Assertion [A]: For the matrix Reason [A]: For any matrix A, AI = IA = A.
question_answer5) Assertion [A]: Matrix is a skew symmetric matrix. Reason [R]: A matrix A is skew symmetric if \[A'=A\].
question_answer6) Assertion [A]: Matrix is a symmetric matrix. Reason [R]: A matrix A is symmetric if \[A'=-A\].
question_answer7) Assertion [A]: For two matrices and \[{{\left( A+B \right)}^{2}}={{A}^{2}}+2AB+{{B}^{2}}\]. Reason [R]: For given two matrices A and B, AB = BA.
