Exponential Command
From GeoGebra Manual
- Exponential( <Lambda>, x )
- Creates cumulative density function (cdf) of exponential distribution with parameter lambda.
- Exponential( <Lambda>, x, <Boolean Cumulative> )
- If Cumulative is true, creates cumulative distribution function (cdf) of exponential distribution, otherwise creates pdf of Exponential distribution.
- Exponential( <Lambda>, <Variable Value> )
- Calculates the value of cumulative distribution function of Exponential distribution at variable value v, i.e. the probability P(X ≤ v) where X is a random variable with Exponential distribution with parameter lambda.
- 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 Syntax
- Exponential( <Lambda>, <Variable Value> )
- Calculates the value of cumulative distribution function of exponential distribution at variable value v, i.e. the probability P(X ≤ v) where X is a random variable with Exponential distribution with parameter lambda.
- Example:
Exponential(2, 1)
yields 1 - \frac{1}{e^{2} } , which is approximately 0.86.
