WebShow that all tangent planes to the surface z = xf(y=x) intersect at a common point. Find the coordinates of the common point. Solution: The surface is the level set g(x;y;z) = 0, where g(x;y;z) = xf(y=x) z. The normal to the surface is then given by the gradient rg. Using chain rule we compute @g @x = f y x y x f0 y x ; @g @y = f0 y x : WebThis equation shows that the vector Fz;Fy;Fz is the normal vector of the tangent plane. Note. If f(x;y)=k is the equation of a curve in the plane xy, then similarly one can show that the equation of the tangent line at (a;b) is: fx(a;b)(x a)+fy(a;b)(y b)=0 Example.
