mathematical constants

Pi and e

Mathematical constants are fixed numerical values that arise naturally in mathematics and remain unchanged regardless of context.

Pi (π) represents the ratio of a circle's circumference to its diameter.

Euler's number (e) is the base of natural logarithms.

The golden ratio (φ) appears in geometry and art.

These values recur across seemingly unrelated fields—physics, engineering, finance—suggesting deep structural features of mathematics itself.
