Normal line to paraboloid tangent plane.

3D diagram illustrating a paraboloid with a tangent plane at point (1,1,7)(1,1,7) and a dashed normal line extending perpendicularly through the point of contact. The x, y, and z-axes mark the coordinates.

This diagram illustrates the geometry of a tangent plane and normal line on a paraboloid in a 3D coordinate system. The image depicts a paraboloid surface, represented as a smooth, upward-opening shape. A tangent plane intersects the paraboloid at a specific point, and the normal line is shown as a vertical dashed line, representing the direction perpendicular to the tangent plane.

This illustration is ideal for calculus and analytical geometry textbooks and online courses.
