Tangent plane in 3D
Hello
I would like to draw a tangent plane to a function in 3D APP. I work in CAS mode in the following example: For example FZ1(X,Y)=X^1/3 * Y^1/3: I introduce this equation in "Symbolic View" in de 3D APP. It draws it correctly when I press "Plot". Then I introduce the plane equation in a point (for example (1,1)): FZ2(X,Y)=FZ1(1,1)+dFZ1(X,Y)/dX * (X1) + dFZ1(X,Y)/dY * (Y1) When I press Plot it does not draw the plane. I have tried to derivate it directly dFZ1(X,Y)/dX and it gave me 0, Could somebody give me an idea to how to trace that plane? Thanks very much Toni
