Matrices and Determinants

Exercise 3.3
Question 1: Find the transpose of each of the following matrices:  Question 2: We have  Question 3:     Question 4: Question 5: For the matrices A and B, verify that (AB)′ = B'A' where   Question 6:  (ii)  Question 7:   Hence, A is a skew-symmetric matrix.

Question 8:  Question 9:   Question 10: Express the following matrices as the sum of a symmetric and a skew symmetric matrix:           Question 11: If A, B are symmetric matrices of same order, then AB − BA is a
A. Skew symmetric matrix
B. Symmetric matrix
C. Zero matrix
D. Identity matrix

A and B are symmetric matrices, therefore, we have: Thus, (AB − BA) is a skew-symmetric matrix.

Question 12:
If if the value of α is  The document NCERT Solutions, Matrices, Part -3, Class 12, Maths Notes - Class 12 is a part of Class 12 category.
