Find the absolute maximum and minimum values of f (, y) = { (73 – 1 – y2) + 3 on the region R= {(z,y) : 22 + y2 < 1} (the closed disk centered at (0, 0) with radius 1). = : SOLUTION We begin by locating the critical points of f on the interior of R. The critical points satisfy the equations f1(x, y) = = (3x2 - 1) = 0 and fy (2, y) = -y=0, which have the solutions 2 = + 1 and y = 0.
