BinomialCoefficient Command
From GeoGebra Manual
- BinomialCoefficient( <Number>, <Number> )
- Calculates the binomial coefficient n \choose r . The first Number represents all elements n and the second Number represents the selected elements r.
- Example:
BinomialCoefficient(5, 3)yields 10.
Hint: If your input in the 
CAS View contains undefined variables, then this command yields a formula for the binomial coefficient.
- Example:
BinomialCoefficient(n, 3)yields \frac{n^{3} - 3 n^{2} + 2 n}{6}.
Note: See also NPr command.
