Normal distribution functions

PDFNormal(x,mean,sd)

PDFNormal(x,mean,sd) returns the probability density at the value x of the normal distribution with given mean and standard deviation sd.

Calculator

Graph

Function:	PDFNormal(,,)
	X-axis	Y-axis
Minimum:	Minimum X	Minimum Y
Maximum:	Maximum X	Maximum Y

Enter the argument(s) for the function, including the symbol x.
Enter the minimum and maximum for the X-axis and for the Y-axis.
To let the software define the Y-axis automatically, leave both input fields for the Y-axis empty.

CDFNormal(x,mean,sd)

CDFNormal(x,mean,sd) returns the value at x of the normal cumulative distribution with given mean and standard deviation sd.
