Does there exist a plane targent to x^2−2y^2 +2z^2 = 8 and which passes through 2x+3y+2z = 8, x−y+2z = 5? Justify your answer.

Determine the square of the arc element for the curvilinear coordinate system
(u,v,w) whose coordinates are related to the Cartesian coordinates as follows:
x = 3u + v − w; y = u + 2v + 2w;z = 2u − v − w.

Coordinates whose curves are mutually perpendicular at each point are called …………
Cylindrical Coordinates
Spherical Coordinates
Orthogonal Curvilinear coordinates
Ellipsonic Cylindrical Coordinates
