Hockey Stick Identity Brilliant Math & Science Wiki
In combinatorial mathematics, the hockey-stick identity, [1] Christmas stocking identity, [2] boomerang identity, Fermat's identity or Chu's Theorem, [3] states that if n โฅ r โฅ 0 are integers, then. ( r r) + ( r + 1 r) + ( r + 2 r) + โฏ + ( n r) = ( n + 1 r + 1). The name stems from the graphical representation of the identity on Pascal's.

This paper presents a simple bijection proof between a number and its combina-torial representation using mathematical induction and the Hockey-Stick identity of the Pascal's triangle. After stating the combinadic theorem and helping lemmas, section-2 proves the existence of combinatorial representation for a non-negative natural number.

example 5 Use combinatorial reasoning to establish the Hockey Stick Identity: The right hand side counts the number of ways to form a committee of people from a group of people. To establish this identity we will double count this by assigning each of the people a unique integer from to and then partitioning the committees according to the.

Application This identity is used in problem 660E - Different Subsets For All Tuples. Leave a comment if you know other problems for it. In practice Naturally, if we want to calculate the binomial, we can for example use the formula $$$ \displaystyle \binom {n} {k} = \frac {n!} {k! (n-k)!} $$$ and do the division using modulo-inverse.
