Q11 of 124 Page 213

If then find the least value of α for which A + A’ = I.

Given,

Here, A’ i.e. A transpose is

We are given that A+A’=I

So,

After doing addition of matrices, we get,

On comparing the elements we get,

This implies,

For belongs 0 to , =

Show that

If and find the matrix C such that A + B + C is a zero matrix

Find the value of x and y for which
