e-x Calculator



Formula

The formula to calculate the value of \( e^{-x} \) is:

\[ e^{-x} = 2.71828^{-x} \]

Where:

What is \( e^{-x} \)?

The value of \( e^{-x} \) is calculated by raising Euler's number (approximately 2.71828) to the power of the negative value of \( x \). This is a common calculation in mathematics, particularly in fields such as calculus and differential equations.

Example Calculation

Let's assume the following value:

Step 1: Calculate the value of \( e^{-x} \):

\[ e^{-2} = 2.71828^{-2} \approx 0.13534 \]

Therefore, the value of \( e^{-2} \) is approximately 0.13534.
