Python | sympy.rf() method
With the help of sympy.rf() method, we can find the Rising factorial. Rising factorial is defined by –
where x can be arbitrary expression and k is an integer.
Syntax: rf(x, k)
x – It denotes any arbitrary expression.
k – It denotes an integer.
Returns: Returns rising factorial corresponding to the given inputs.
Value of x = x and k = 5 Rising factorial rf(x, k) : x*(x + 1)*(x + 2)*(x + 3)*(x + 4)
Value of x = 7 and k = 5 Rising factorial rf(x, k) : 55440
