normal of vs normal to

Both 'normal of' and 'normal to' are correct, but they are used in different contexts. 'Normal to' is the more common and standard phrase used to describe a line or plane that is perpendicular to another line or plane. On the other hand, 'normal of' is used in mathematical contexts to describe the normal vector of a surface or object.

normal of

This phrase is correct in mathematical contexts to describe the normal vector of a surface or object.

This phrase is commonly used in mathematics to refer to the vector that is perpendicular to a surface or object. It is used to calculate angles, distances, and other geometric properties.

Examples:

The normal of the plane is pointing in the positive z-direction.
The normal of the cube is a vector perpendicular to all its faces.
In 3D graphics, the normal of a polygon is crucial for shading calculations.
The normal of the sphere at a given point is the radial vector from the center.
Calculating the normal of a curve requires knowledge of calculus and vector algebra.
