Really helpful

[@drummerdude0011]

Thank you David!

[@ahmadk5844]

thank you for this video.. what if the surface looks like this : 2x^2 + 8y^2 + z = 2 ?

[@mistymouse6840]

That is an upside down elliptic paraboloid, with vertex at (0,0,2). It intersects the x-y plane in an ellipse with major axis along the x-axis of length 2, and minor axis along the y-axis with length 1.

[@lenaphilippe4131]

Thank you for the video ! How do we know that the parabola on the x=0 plane is sideways ?

[@fungiuse]

just turn your computer sideways !! It will be vertical

I can't hear your voice

[@davidmetzler]

I don't see any problem with the audio, so probably an issue on your end.
