Beta distribution functions

PDFBeta(x,a,b)

PDFBeta(x,a,b) returns the probability density at the value x of the Beta distribution with parameters a and b.

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

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.

CDFBeta(x,a,b)

CDFBeta(x,a,b) returns the value at x of the cumulative Beta distribution with parameters a and b.

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.

RndBeta(a,b)

RndBeta(a,b) returns a random number of the Beta distribution with parameters a and b.
