Best,j3n nyIs B=A^2 skew-symmetric, symmetric or neither?

Hey,

I need help with thris proof.. :)

Say A is a skew-symmetric matrix. Is B=A^2 skew-symmetric, symmetric or neither. Prove your answer.



I know it's symmetric, but I'm having problems with subscriptmanship. Can anyone help me out?

Thanks,
j3n

Here's a starting point:
A=-A^\top
