Homework Help: To:BobPursley

Posted by Shadow on Thursday, September 9, 2010 at 9:51pm.

Earlier you told me "hold a pencil up. A real pencil. I bet you can make perpendiculars in many directions, because the pencil is in a three dimensional space". Could you explain to me what do you mean by this? I try holding up a pencil and doesn't see anything.Thanks
