Prove that the acute angle [tex]\gamma[/tex] between the z axis and the normal to the surface F(x,y,z)=0 at any point is given by [tex]sec \gamma = \frac{\sqrt{F_x^2 +F_y^2+F_z^2}}{|F_z|}}[/tex]
Where i am having trouble is that i do not know what this surface is, can someone help clarify what the surface is. thanks
