Exponential[ <Mean λ>, x ]
Creates probability density function (pdf) of exponential distribution with mean λ.
Exponential[ <Mean λ>, x, <Boolean Cumulative> ]
If Cumulative is true, creates cumulative density function of exponential distribution, otherwise creates pdf of Exponential distribution.
Exponential[ <Mean λ>, <Variable Value v> ]
Calculates the value of cumulative distribution function of Exponential distribution at v, i.e. the probability P(X≤v) where X is a random variable with Exponential distribution with mean λ.
Note: Returns the probability for a given x-coordinate's value (or area under the Exponential distribution curve to the left of the given x-coordinate).

CAS Syntaxes

In CAS View only following syntax is supported:

Exponential[ <Mean λ>, <Variable Value v>]
Calculates the value of cumulative distribution function of exponential distribution at v, i.e. the probability P(X≤v) where X is a random variable with Exponential distribution with mean λ.
