 # Exponential Distribution Calculator

<-- Enter x
<-- Enter λ

### How does the Exponential Distribution Calculator work?

Calculates the Probability Density Function (PDF) and Cumulative Density Function (CDF) of the exponential distribution as well as the mean, variance, standard deviation, and entropy.
This calculator has 2 inputs.

### What 6 formulas are used for the Exponential Distribution Calculator?

1. ƒ(x,λ) = λe-λx
2. F(x,λ) = 1 - e-λx
3. μ = 1/λ
4. Median = Ln(2)/λ
5. σ2 = 1/λ2
6. Entropy = 1 -Ln(λ)
