The symbol "∧" is proportional. The proportional relationship between one physical quantity Y and another physical quantity X can be expressed as y∝x (read as "Y is proportional to X"). For example, in the velocity formula v=s/t of uniform motion, S is directly proportional to T, which is denoted as S ∝ T. ..
Definition of "":Special symbols refer to symbols that use fewer characters than traditional or commonly used symbols and are difficult to input directly, such as mathematical symbols (used before chapters to indicate new chapters); Unit symbol; Tab, etc.

Definition of "∝": Since there is no special symbol for inverse proportion, we can also use the symbol "∝" with reciprocal to represent inverse proportion. For example, ohm's law I=U/R, and when u is constant, I is inversely proportional to R. At this time, we can write I ∝ 1/R, and the symbol "∝" (which has nothing to do with the infinite symbol "∞") indicates that there is a certain proportional relationship between two physical quantities. Because the proportional relationship is the simplest relationship between physical quantities, it will often be encountered in the study of this topic. This symbol is sometimes used to clearly or concisely express the relationship between certain quantities. For another example, the linear resistance r of a conductor is proportional to the length l of the conductor, which can be expressed as: r ∝ l; It is also inversely proportional to the cross-sectional area s of the conductor, which can be expressed as: r ∝1/S. As we know, it should also be related to the resistivity ρ of the material used to make the conductor.
