Primage \Pri"mage\ (?; 48), n. [F.] (Com.)
A charge in addition to the freight; originally, a gratuity

  • Pascals Triangle and Binomial Coefficients
    Prove that binomial coefficients (the actual coefficients of the expansion of the binomial \((x+y)^n\)) satisfy the same recurrence as Pascal's triangle At last we can rest easy that can use Pascal's triangle to calculate binomial coefficients and as such find numeric values for the answers to counting questions
  • Why does Pascals Triangle give the Binomial Coefficients?
    An exercise in chapter 2 of Spivak's Calculus (4th ed ) talks about how Pascal's triangle gives the binomial coefficients It explains this by saying that the relation $\binom{n+1}{k} = \binom{n}{k-1}+\binom{n}{k}$
  • Pascals triangle - Art of Problem Solving
    Pascal's triangle is a triangle which contains the values from the binomial expansion; its various properties play a large role in combinatorics These are the first nine rows of Pascal's Triangle Pascal's Triangle is defined such that the number in row and column is
  • Pascal’s Triangle – Patterns, Formula, and Binomial Expansion
    In Pascal’s Triangle, each number represents the coefficient of the terms of binomial expansion (x+y) n, where x and y are any two variables and n = 0,1,2,…… Now expanding (x+y) n , we get, (x+y) n = a 0 x n + a 1 x (n-1) y + a 2 x (n-2) y 2 +……… +a (n-1) xy (n-1) + a n y n
  • Pascal’s Triangle and Binomial Coefficients
    From that context, we introduce a notation for each of the numbers in the triangle: The number in row \(n\) and (diagonal) column \(k\) (both starting at \(0\)) is denoted by \(\binom{n}{k}\) and is read as “ \(n\) choose \(k\) ” and also called a “Binomial Coefficient”:
  • The binomial theorem and related identities - MIT Mathematics
    triangle We start with 1 at the top and start adding number slowly below the triangular Help you to calculate the binomial theorem and find combinations way faster and easier Binomial coefficient 4 2
  • Combinations, Pascals Triangle and Binomial expansions
    Somewhere in our algebra studies, we learn that coefficients in a binomial expansion are rows from Pascal's triangle, or, equivalently, (x + y) n = n C 0 x n y 0 + n C 1 x n - 1 y 1 + … + n C n x 0 y n But why is that? Why are the coefficients related to combinations?
