4) Three friends are working on a problem concerning a differentiable function f(x,y,z) at a point P. While these 3 people are discussing their calculations: 1st person says: "I found the equation of the tangent plane to the surface f(x, y, z)=c at the point P to be 3x + 6y – 2z =9". 2nd person says: "I discovered that the maximum value of the directional derivative of the function f at the point P is 5" 3rd person says:...
