The latin letter in is used in math to represent Euler’s Number. Euler’s number is a constant related to exponential growth that appears in many formulas and math equations as shorthand for the exponential function and as the base of the natural logarithm function.
The capital Latin letter E.
Euler's number is a naturally occurring number related to exponential growth and exponential decay. It is also shorthand for the exponential function.
Returns the natural logarithm of the input number. The natural logarithm function is the inverse of the exponential function.
