Greek symbols are used as symbols in mathematics, physics and other sciences. Many symbols have traditional uses, such as lower case epsilon (ε) for an arbitrarily small positive number , lower case pi (π) for the ratio of the circumference of a circle to its diameter , capital sigma (Σ) for summation , and lower case sigma (σ) for standard ...
Going back to the holiday's roots, the mathematical symbol Pi is the ratio of the circumference of a circle to its diameter. The value of Pi is approximately 3.14, but it has infinite decimal ...
