I've used differentiation to find that a rectangular enclosure made up of a 100m fence should have four sides all 25m to be as large as possible. The function I get is [tex]50x-x^2[/tex]. As I said, differentiating this function gives me the largest area possible. But how would I go about finding how long the sides must be in order to make the area as small as possible...?
