Question
(a) Find an equation of the tangent plane to the surface of z = ye(3zy-y³) at
(-1, –3, –3).
(b) Given that the function z = f(x, y) is a differentiable function with
f(2, –3) = 5, f= (2, –3) = -2, fy(2, –3) = 6, find the linear approximation and
the differential of the function at (2,-3). Use the differential to estimate the total
change Az when x is increased by 0.1, and y is decreased by 0.03. Enter your
answer in the blank below. Round your answer to two decimal places.
