The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter Ï, sometimes spelled out as pi. In English, Ï is pronounced as pie (/paÉª/ , paÉª).
Graphs like this are among the objects studied by discrete mathematics, for their interesting mathematical properties, their usefulness as models of real-world problems, and their importance in developing computer algorithms. Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.
