questions - permutations, GAD (1 Viewer)

[steverulz55]

there's many proofs you can make your own

e.g.
by considering the identity (1+x)^8 (1+x)^8 = (1+x)^16
prove (8c0)^2 + (8c1)^2 +......+(8c8)^2 = 16c8

i wonder where you got this question from da

lol thats just my question for n=8
i forgot where that was from...some past paper?

 

[Rorix]

it was from the paper with bruce tossing............................coins.

lol
what a cool thread

anyway, if you wish to have those proofs/whatever, have a look at fatmuscle's binomial article. I think you'll find everything you'll need there.

I <i>think</i> anyway. :-\

hey! How come all you guys are helping out when some cherryblossom GIRL (of all things) asks for help in the forum? @__@ When I ask questions, none of you help me as much. :'(
