on the region (a) Find the critical points ofwc inside M and classify them as local min, local max or saddle pt. (b) Now nd the maximum and minimum values of f on the portion of M on the xy plane. This is the equator disk: '5' : {("'~Uv U) : ii; Whose boundary 08 is a circle of a radius (c) Now use the method of Lagrange multipliers to find the maximum and minimum values of f in the whole region M, listing all points at which those values occur
