Q4 of 43 Page 1

If and then find A^T – B^T.

As we know that, transpose of a matrix is given by interchanging the rows with the respective columns.

∴ Transpose of Matrix B = B^T =

The difference of transpose matrices of A & B is –

A^T – B^T =

⇒ A^T – B^T =

The required difference is

Find the principal value of tan^–1√3 - sec^–1 (-2).

Find the value of x + y from the following equation:

Let A be a square matric of order 3 × 3. Write the value of |2A|, where |A| = 4.

Evaluate:

If and then find AT – BT.
