prove the above identity using a combinatorial arg
2019年1月10日 — To give a combinatorial proof for a binomial identity, say A=B you do ... in Pascal's triangle, we can rewrite the above observations as follows: ... One option would be to give algebraic proofs, using the formula for (nk): ... The bit s,The above result can be proved using induction. Is there an algebraic way of proving the above result? More importantly, is there an intuitive "combinatorial ... ,A combinatorial identity is proven by counting the number of elements of some carefully chosen set in two different ways to obtain the different expressions in the identity. Since those expressions count the same objects, they must be equal to each other ,Any entry not on the border is the sum of the two entries above it. The triangle is symmetric. ...
