e Calculator | eˣ | e Raised to Power of x
Are you solving an equation with Euler's number? Our e calculator is here to help! Our tool allows you to compute e to the power of any number you desire.
Keep on reading if you're still wondering what exactly Euler's number is, what does e mean on a calculator, and how to calculate e to the x 📐🧑🏫
What is e on a calculator? - e to the x
e is one of the most important constants in mathematics. We cannot write e as a fraction and it has an infinite number of decimal places - just like its famous cousin, pi (π).
e has plenty of names in mathematics. We may know it as Euler's number or the natural number. Its value is equal to 2.7182818284590452353602.. and counting! (This is where rounding and approximation become essential.) 🧮
Since we already know what e and its approximate value is, we can start thinking about its possible applications.
e is the base of the natural logarithm.
We use e in the natural exponential function (ex = e power x).
In the ex function, the slope of the tangent line to any point on the graph is equal to its y-coordinate at that point.
(1 + 1/n)ⁿis the sequence that we use to estimate the value of e. The sequence gets closer to e the larger n is - but even if n = infinity, the sequence value is not equal to Euler's number.
We use this equation in compound interest calculations.
- e is equal to the result of the following factorial equation:
- e is also a part of the most beautiful equation in mathematics:
eiπ + 1 = 0🌺
Since we already know what's the Euler's number, how about some other numbers we use in physics?
How to put e in a calculator? Calculate e to the x
Since we're forced to use an approximation of e, we can simply input the value of e into any calculator.
How does it work in practice? How to calculate e to the power x?
If your calculator doesn't allow symbols, simply enter 2.718281828 (or any rounded form of this number) into your choice value box 👍
e calculator - examples
In this section we'll answer the very big question: "How to calculate e to the power
ex?" using both our calculator and the traditional formula.
The e calculator - it's so simple it doesn't need further explanation. Enter the value of x into the text box and enjoy your results displayed alongside the step-by-step solution 👣
The traditional calculation requires you to choose how many decimal places of the Euler's number you are going to use.
We decided to use 9 decimal places.
Let's follow an example:
We know that the area up to any x-value is also equal to ex:
We'd love to calculate the area up to the e10 function.
e10 = 2.71828182810
2.71828182810 = 2.718281828 * 2.718281828 * 2.718281828 ...
2.71828182810 = 22026.47
And this is how to calculate e to the power of 10.
As you can see, calculating e to the power of x might be quite troublesome and time-consuming - our tool is a simple solution for that unnecessary problem 🤗
