As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
The symbol was introduced originally in 1770 by Nicolas de Condorcet, who used it for a partial differential, and adopted for the partial derivative by Adrien-Marie Legendre in 1786.

Note: The empty set symbol ∅ looks similar, but is unrelated to the Greek letter. or represents: the golden ratio 1.618... in mathematics, art, and architecture; Euler's totient function in number theory; the argument of a complex number in mathematics; the value of a plane angle in physics and mathematics
Example of a nineteenth-century font using turned-lamedh-shaped capital Koppa and G-shaped capital Stigma. Stigma and Koppa in modern fonts. Throughout much of its history, the shape of digamma/stigma has often been very similar to that of other symbols, with which it can easily be confused.
