questions below:

Suppose that the Celsius temperature at the point (x,y,z) on the sphere x2 + y2 + z2 = 1 is T = 1200xyzz. Locate the highest and lowest temperatures on the sphere. ...) The highest temperature on the sphere is C. (Simplify your answer.) The lowest temperature on the sphere is DC. (Simplify your answer.) Use Taylor's formula for f(x,y) at the origin to find quadratic and cubic approximations of f(x,y) = 8x e By near the origin. . . . The quadratic approximation of f(x,y) is The cubic approximation of f(x,y) isUse Taylor's formula for f(x,y) at the origin to find quadratic and cubic approximations of f near the origin. f(x,y) = 4 sin x cos y The quadratic approximation is The cubic approximation is
