For the z, direction, it’s clearly between z= 0 and z= x2 y2 The double integral formulation is ZZ R (x2 y2 0)dA The triple integral formulation is ZZZ T dV = Z 1 y= 1 Z x=1 2y x=y 1 Z x y2 0 dzdxdy 3Evaluate the volume bounded by the paraboloid z= x2 y2 and the plane z= y 2 This problem is tricky It’s on the book It’s one. Solution to Problem Set #9 1 Find the area of the following surface (a) (15 pts) The part of the paraboloid z = 9 ¡ x2 ¡ y2 that lies above the x¡y plane ±4 ±2 0 2 4 x ±4 ±2 0 2 4 y ±4 ±2 0 2 4 Solution The part of the paraboloid z = 9¡x2 ¡y2 that lies above the x¡y plane must satisfy z = 9¡x2 ¡y2 ‚ 0 Thus x2 y2 • 9 We.

Solve the first two for z x²y=z y²x=z x²y = y²x, since both equal to z x²y² = xy (xy)(xy) = (xy) We will see if we can divide by xy We will first assume xy ≠ 0 Then we can divide both sides by xy and get xy = 1 But since z²=xy, then that would mean z²=1 and z would be ±i. Plot x^2 3y^2 z^2 = 1 WolframAlpha Assuming "plot" is a plotting function Use as referring to geometry. From ∂z/∂x = −ysin(x−y) and ∂z/∂y = cos(x−y)ysin(x−y), it follows that ∂z/∂x(2,2) = 0, ∂z/∂y(2,2) = 1, and hence the tangent plane to z = ycos(x−y) at (2,2,2) is given by z−2 = 0·(x−2)1·(y−2) or, equivalently, y = z Exc The (first) partial derivatives of f(x,y) =.
