Is $(\mathbf{V} \cap \mathbf{W})^{\bot}=(\mathbf{V}^{\bot} \cap \mathbf{W}^{\bot})$? I tried element-chasing, but I am getting confused when trying to determine mutual containment.

    Try examples. Try at least a few examples to see if it works.2011-02-21

    Guilty... Maybe I should temporarily hide it, but I suppose it's too late. Dear Jared, I hope that I have not ruined your joy of discovery.2011-02-21

    By the way, $\LaTeX$'s way to say 'perpendicular' is `\perp` (which gives a $\perp$) and not `\bot` (which results in a $\bot$)2011-02-21

    No. You should have union on the right hand side2014-04-23
