Gamma distribution functions

PDFGamma(x,a,b)

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

Calculator

Graph

Function:	PDFGamma(,,)
	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.

CDFGamma(x,a,b)

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