I am currently brushing on my linear algebra skills when i read this(adsbygoogle = window.adsbygoogle || []).push({});

For any Matrix A

1)A*At is symmetric , where At is A transpose ( sorry I tried using the super script option given in the editor and i couldn't figure it out )

2)(A + At)/2 is symmetric

Now my question is , why should it be divided by 2? doesnt just A + At alone give a symmetric matrix
