Question

Lets see if you can answer this:
If matrix A = [1 2 3], write AA’, where A’ is the transpose of matrix A.

Answer 1

Question :

If matrix A =[1 2 3 ] , write AA' ,where A' is transpose of matrix A .

Theory :

The matrix obtained From a given matrix A by changing its rows into columns into rows is called transpose of matrix A , it is denoted by A'.

⇒if order of A is m×n ,then order of A' is n×m

Example : Transpose of matrix

$\left|\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right|$ is

$\left|\begin{array}{ccc}1&4&7\\2&5&8\\3&6&9\end{array}\right|$

Solution :

Given : matrix A =[ 1 2 3]
