∝ is directly proportional to, which is very common in physics. For example, a∝b means that when a increases, b also increases.

There are other symbols:

∈ Belongs to symbols, indicating the subordinate relationship between elements and sets.

∏ orthogonal symbol

Sigma summation symbol

∕ Equivalent to division \u

√ Arithmetic square root, if the square of 2 is 4, then the arithmetic square root of 4 is 2.

∞ infinity indicates the trend, and +∞ indicates the growth trend.

Right angle symbol

∠ Angle symbol

∣ Absolute value sign and division sign

Describe the relationship between two parallel straight lines.

The basic symbol of cross-symbolic logic means that two propositions are established at the same time.

The basic symbol of union symbolic logic, indicating that one of the two propositions is true.

The basic symbol of the intersection symbol set, indicating that two sets intersect at the same time.

∪ The basic symbol of the union symbol set, which means that at least one set is satisfied.

∮ Integral symbol The basic symbol of calculus

therefore ...

because

Proportional symbol

proportion

∽ The basic symbols belonging to the symbol set describe the subordinate relationship between the two sets.

≈ approximately equal to symbol

≌ Similar symbols depict the basic characteristics of set graphics.

≈ The equal sign describes the relationship between two relationships.

What is the difference between the two?

≡ The basic symbol of congruence symbol number theory means that two integers divided by the same specific integer are equal, for example, 5=2×2+ 1, 7=2×3+ 1, then 5≡7 (mod 2).

≤ Not greater than the relationship number, the former is less than or equal to the latter.

≥ not less than relative symbol, the former is greater than or equal to the latter.

≤ is much less than or equal to the relational sign, and the former is much less than or equal to the latter.

≥ much greater than or equal to the relational symbol, the former much greater than or equal to the latter.

Not less than the same or more

≯ Not greater than the same or less than.
