(10 points) Consider the following function. f(x, y) = tan-1 Apply the Taylor's Theorem with n = 2 and (a, b) = (1, 0) to the function f, see Hint . Use t E (0, 1) as a certain constant for the remainder. f ( x, y) = 2y-xy Hint: (Taylor's Theorem with n = 2) Let the function f : 2 -> R be of class C2 around (a, b). Then there exists t E (0, 1) such that a a f(x, y) = f(a, b) + 1 ! (ac - a a + (y - b a ay f (a, b ) + 2 ! (ac a ) + - b) ax flat t(x - a), b + t(y - b)). Ox ay
