Find the linearization L(x,y) of the function f(x,y) = x2- 9xy + 1 at Po(3,3). Then find an upper bound for the magnitude | E| of the error in the approximation f(x,y) ~ L(x,y) over the rectangle R: |x - 3| $0.3, ly - 3| $0.3. . . . The linearization of f is L(x,y) =By about how much will f(x,y,z) = In vx+ y + z change if the point P(x,y,z) moves from Po(4,5,15) a distance of ds = 0.1 unit in the direction of 3i + 6j - 2k? The change in value is about df ~ (Round to four decimal places.)Part 1 0f3 Find parametric equations for the line tangent to the curve of intersection of the surfaces at the given point. Surfaces: x+y2 +2z=8. x=3 Point: (3,1,2) L - Find the equations for the tangent line. Let z = 2 2t. FD
