Use Lagrange multipliers to find the lengths of the major and minor axes of the ellipse 2x2 +xy + 2 = 15, which has centre at the origin. A major axis 6v2. minor axis 312 B major axis 12v2. minor axis 8 fa ( major axis 8v2, minor axis 4 fa D major axis 10v2, minor axis 6 42 E major axis 512. minor axis 312
