please help me about this
get Equation of the tangent plane on the surface(x^2-2y^2+2z=4) on p0(x0,y0,z0) and then find a point that tangent plane on the curve on this point is Horizontal ?
i get the Equation of the tangent on the surface(x^2-2y^2+2z=4) on p0(x0,y0,z0)
[URL]http://latex.codecogs.com/gif.latex?\bigtriangledown%20f=(2x_{0},-4y_{0},2)[/URL]
and the P equation is [URL]http://latex.codecogs.com/gif.latex?2x_{0}x-4y_{0}y+2z=2z_{0}+2x_{0}^2-4y_{0}^2[/URL]
but how can i find a point that tangent plane on the surface on this point is Horizontal ??
plaese help and sorry for my bad english
