Representation of n as 2n!/(2n-1)!-n!/(n-1)! is not a sin. It is practical.
We do realize that we have 2 legs. We do say 50 steps away. We do hold the cheque with left hand and sign the cheque with right hand.
Why not 2n -n at the most? Maximum permissible!!
Gamma function is the reason.
A car has a tyre circumference 1 metre. How many revolution did the tyre make when it travels 400 metro?
ReplyDeleteAgreed n is used here.
But more importantly it is a person who gives these problems.
Because of presence of man gamma expression is more important.
2n!/(2n-1)!-n!/(n-1)! is important.
There are interesting results in my expressions.
ReplyDeleten is more interesting than either 2n -n or for that matter 2n!/(2n-1)!-n!/(n-1)!.
I loose.
