express z in terms of t and find dzdt .

2. Suppose that z is a function of x and y, implicitly related by the equation

x2/4+y2+z2/9=3

Find the equation of the tangent plane to the surface f(x,y,z)=3 (surface of ellipsoid) at the point where (x,y)=(−2,1,−3). Then determine the linear approximation to function z in vicinity of (x,y)=(−2,1) and use it to find the approximate value of z(−2.1,1.1)
