Symmetry of origin is widely used in mathematics and physics. In the function image, odd function is symmetrical about the origin, that is, the images of odd function on both sides of the origin are mirror images. This symmetry is also very important in physics, when studying the physical system of symmetry and analyzing waveforms.
Origin symmetry is a basic geometric concept, which describes a special relationship between two points on a plane and is symmetrical about the origin of the coordinate system. This symmetry is widely used in mathematics and physics, and it is an important tool to understand and analyze complex phenomena.
