- Normal( <Mean>, <Standard Deviation>, x )
- Creates probability density function (pdf) of normal distribution.
- Normal( <Mean>, <Standard Deviation>, x, <Boolean Cumulative> )
- If Cumulative is true, creates cumulative distribution function of normal distribution with mean μ and standard deviation σ, otherwise creates pdf of normal distribution.
- Normal( <Mean μ>, <Standard Deviation σ>, <Variable Value v> )
- Calculates the function \Phi \left(\frac{x- \mu}{\sigma} \right) at v where Φ is the cumulative distribution function for N(0,1) with mean μ and standard deviation σ.
- 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).
- Example:
Normal(2, 0.5, 1)yields 0.02 in the
Algebra View and \frac{erf(-\sqrt{2})+1}{2} in the 
CAS View.
