Solved: In Exercises 45–48, find the linearization L(x, y,

Chapter 13, Problem 46E

(choose chapter or problem)

In Exercises , find the linearization \(L(x,y)\) of the function \(f(x,y)\) at \(P_{0}\. Then find an upper bound for the magnitude of the error \(E\) in the approximation  \(f(x, y) \approx L(x, y)\) over the region \(R\).

\(f(x, y, z)=x^{2}+x y+y z+(1 / 4) z^{2} \text { at } P_{0}(1,1,2)\) ,

\(R:|x-1| \leq 0.01,|y-1| \leq 0.01,|z-2| \leq 0.08\)
