for all you math studs out there, here is a little calculus problem to work out for fun...
A fence 8 feet tall stands on level ground and runs parallel to a tall building. If the fence is 1 foor from the building, find the length of the shortest ladder that will extend from the ground over the fence to the wall of the building. (Hint 1: if L represents the length of the ladder, the quantity L is minimized when the quantity L^2 is minimized, so you do not have to concern yourself with the square root--just minimize L^2 and that will minimize L. Hint 2: use similar triangles.)
