BETA function

Description

BETA(a,b) returns the Beta function of a and b.

The BETA function is defined by:

$$ \mathrm{Beta}(a,b) = \int_0^1t^{a-1}(1-t)^{b-1}\,\mathrm{d}t $$

Both arguments a and b must be larger than 0.

The argument a can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the BETA function applied to all elements.

Graph

Function:	BETA(,)
	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.
