If , find x satisfying when A + A^T = I.

Given:

To find: x

Firstly, we find the A^T

So,

It is given that A + A^T = I when

So,

Comparing both the matrices, we get

2cosx = 1

If , find A + A^T.

If , write A².

If , find AA^T.

If , where I is 2 × 2 unit matrix. Find x and y.

If , find x satisfying when A + AT = I.
