This seems like it should lead somewhere.

1) Pick one red rectangle.

2) Draw a radius to each of its two distant corners.

3) Define the area of the rectangle as a function of the interior angle so defined. Pretty obviously, . The area of the rectangle is zero at either exteme.

Now what?

Other ideas? - Jan 29th 2010, 04:54 PMVonNemo19
