9. [8 points] A flat circular plate has the shape of the region x2 + y2 1. The plate, including the boundary where x2 + y2 = 1, is heated so that the temperature at the point (,y) is given by T(x,y) =x2+2y2 -x
Find the points on the plate that are the hottest and the coldest. For the boundary of the plate, use Lagrange Multipliers. To aid in your calculation, note that
