Normal[ <Mean μ>, <Standard Deviation σ>, <x> ]
Creates probability density function (pdf) of normal distribution.
Normal[ <Mean μ>, <Standard Deviation σ>, <x>, <Boolean Cumulative> ]
If Cumulative is true, creates cumulative distribution function of normal distribution, otherwise creates pdf of normal distribution.
Normal[ <Mean μ>, <Standard Deviation σ>, <Variable Value v> ]
Calculates the function Φ((x – μ) / σ) at v where Φ is the cumulative distribution function for N(0,1).
Note: Returns the probability for a given x-coordinate's value (or area under the normal distribution curve to the left of the given x-coordinate).

CAS Syntax

Normal[ <Mean μ>, <Standard Deviation σ>, <Variable Value x> ]
Calculates the function Φ((x – μ) / σ) where Φ is the cumulative distribution function for N(0,1).
Example:
Normal[2, 0.5, 1] yields \frac{\sqrt{2}}{\sqrt{\pi }e²}.
