Chapter 8, Section 8.4, Question 002 Find the partial derivatives fr and fy of the function f (x, y). The variables are restricted to a domain on which the function is defined. f (x,y) = 6x² +9y2 f: (, y) = QU fy (I, y) = QU
Find the first partial derivatives of the function. f(x, y) = 2x + 4y + 8 fy 2 fy = 2 X
Chapter 8, Section 8.4, Question 016 * Your answer is incorrect. Try again. Find all points where the partial derivatives of f(x, y) are both 0, where f(x, y) = 6x2 + 2y2 Input the points separated by ; below. For example: (-1,9); (2,3); (4,2) if there are three points, or (-1,-1) if there is only one point. The point(s) where the partial derivatives of f(x, y) are both are Q

Question 2 (20 points): Consider the functions f(x, y)-xe y sin y and g(x, y)-ys 1. Show f is differentiable in its domain 2. Compute the partial derivatives of g at (0,0) 3. Show that g is not differentiable at (0,0) 4. You are told that there is a function F : R2 → R with partial derivatives F(x,y) = x2 +4y and Fy(x, y 3x - y. Should you believe it? Explain why. (Hint: use Clairaut's theorem) Question 2...
