What is Euler's Number (e)?
Euler's number, denoted as 'e', is a fundamental mathematical constant approximately equal to 2.71828. It is the base of the natural logarithm and appears in many areas of mathematics and science.
It's an irrational number, meaning its decimal representation never ends and never repeats. Euler's number can be defined in various ways, such as the limit of (1 + 1/n)^n as n approaches infinity, or as the sum of the infinite series 1/0! + 1/1! + 1/2! + 1/3! + ....
'e' is crucial in calculus, appearing in exponential growth and decay models, and is fundamental in complex analysis, trigonometry, and number theory. It's as important as π (pi) in mathematics!
