Key =>{binomial, (binomial,ZZ,ZZ)},
Headline => "binomial coefficient",
Usage => "binomial(n,k)",
Inputs => {
"n" => ZZ,
"k" => ZZ => ", must be non-negative"
},
Outputs => {{"the binomial coefficient, the coefficient of ", TT "x^k", " in ", TT "(1+x)^n"}
},
EXAMPLE {"binomial(13,6)",
"binomial(-1,3)"},
Caveat => {"Doesn't do polynomials, things like ", TT "binomial(x,3)",
" where ", TT "x", " is an element of a ring other than", TT " ZZ"},
