1. Prove the hockeystick identity X r n = n + r + 1 + k k=0 k r when n; r 0 by using a combinatorial argument. (You want to choose r objects. For each k: choose the rst r k in a row, skip one, then how many choices do you have for the remaining objects?)

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 โ‰ฅ r โ‰ฅ 0 are integers, then. ( r r) + ( r + 1 r) + ( r + 2 r) + โ‹ฏ + ( n r) = ( n + 1 r + 1). The name stems from the graphical representation of the identity on Pascal's.

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.

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.
