Definition
- The factor multiplying the variable in a term of a binomial expansion. For example, in (x + y)⁴= x⁴+ 4x³y + 6x²y²+ 4xy³+ y⁴the binomial coefficients are 1, 4, 6, 4, and 1. In general, the r-th binomial coefficient in the expression (x + y)^n is : (n,r) = n!/[r!(n - r)!]. (An Etymological Dictionary of Astronomy and Astrophysics, by M.
