360 rotation rule

A rotation of 360 degrees about the origin is equivalent to a rotation of 0 degrees and both are equivalent to the coordinate transformation ( 𝑥 , 𝑦 ) → ( 𝑥 , 𝑦 ) .

What is the rule for rotation?

Here are the rotation rules: 90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y) 270° clockwise rotation: (x,y) becomes (-y,x)

What are the 3 types of rotation?

These rotations are called precession, nutation, and intrinsic rotation.
