## What is mathematical constant e used for?

The number e , sometimes called the natural number, or Euler’s number, is an important mathematical constant approximately equal to 2.71828. When used as the base for a logarithm, the corresponding logarithm is called the natural logarithm, and is written as ln(x) .

### Where is the number e used in real life?

Euler’s number, e , has few common real life applications. Instead, it appears often in growth problems, such as population models. It also appears in Physics quite often. As for growth problems, imagine you went to a bank where you have 1 dollar, pound, or whatever type of money you have.

**What are applications of e?**

e is used to compute the compound interest of a bank account which is compounded continuously. Many integral transformations such as the Fourier Transform and Laplace Transform make use of e to map a function into different domains in order to make its computation more simple.

**Why is e used in so many situations?**

e is used because many computations are easy if you use base e. Think in the derivative of e^x vs a^x. However a^x = e^(c x) for some c. The exponential functions are useful for modeling many systems that occur in our natural world, as well as for modeling economics.

## What is the point of Euler’s number?

It shows up all the time in math and physics, most commonly as a base in logarithmic and exponential functions. It’s used to calculate compounding interest, the rate of radioactive decay, and the amount of time it takes to discharge a capacitor.

### Is E related to pi?

2 Answers. These two numbers are not related. At least, they were not related at inception ( π is much-much older, goes back to the beginning of geometry, while e is a relatively young number related to a theory of limits and functional analysis).

**Who uses Euler’s number?**

Euler’s number has many practical uses, particularly in higher level mathematics such as calculus, differential equations, discrete mathematics, trigonometry, complex analysis, statistics, among others.
