I guess I should have said you look from eyes that are on your feet, but I forgot to say that.]]>http://www.mathisfunforum.com/profile.php?id=11082005-12-17T20:58:42Zhttp://www.mathisfunforum.com/viewtopic.php?pid=20908#p20908I think I understand. Are you saying that your eye-level is exactly the same as the level of the board, and so you see it only as a line?
If so, it the line would seem to get bigger as you walked around it and then get smaller again. If the board was rotating instead of you, it would look like some kind of phantom growy-shrinky line.

Call this the . If you walk around a quarter of a circle and look at the board broad side, then you see the length of the board without any shortening like on an angle. So call this . At the slanted angles in between, it is still the sine of the angle with the length of the board vector. I thought this up because I had a dream last night where I was walking away from someone and I thought to myself, they can't see my face because of the cosine of the angle!! When I woke up I tried to make sense of that!]]>http://www.mathisfunforum.com/profile.php?id=11082005-12-17T16:09:50Zhttp://www.mathisfunforum.com/viewtopic.php?pid=20859#p20859
