hi,

how do i do (2n-1)!/(2n+1)! - Apr 5th 2011, 01:01 AMveileen

Write this way (2n-1)! and (2n+1)!, then simplify and see what remains. - Apr 5th 2011, 01:11 AMsalohcinseah
so for (2n-1)! = 2n-1.2n where else for (2n+1)! = 2n+1.2n ?

O.o No. You really read the first line?

n! = the product of first n natural unzero numbers. So... (2n-1)!=? - Apr 5th 2011, 01:29 AMamul28
salohcinseah,

I guess you din't get what veileen actually said.

See

So

Similarly

So, now divide both and see what remains. - Apr 5th 2011, 01:31 AMsalohcinseah
i see so the answer will be 1/(2n+1)?
