Prove that a square maximizes the area of all rectangles with perimeter P.
In Exercises, find the maximum and minimum of the function f subject to the given constraint. In each case explain why the maximum and minimum must both exist.
In Example 4 we found that the function has stationary points at and
(a) Use the second-derivative test to show that \(f\) has a saddle point at
(b) Use the second-derivative test to show that \(f\) has a relative minimum at
(c) Use the value of \(f(-10,0)\) to argue that \(f\) has a relative minimum at and not an absolute minimum, without using the second-derivative test.
