Prove or disproe:
For any positive integer n and
Say n (>1) is the smallest integer such that for some minimal point ,
On the other hand the critical points for the function are
They are the points in such that
(note that by our finding above)
Thus we get a contradiction and we actually proved that
This is a bit stronger statement.
Thanks Sudharaka for the direction. I thought this problem needs more advanced tech to solve.
We have to show that for any positive integer n and
Therefore the expression is true for n=1
Suppose the expression is true for n=p where
Therefore our the expression is true for
Hence by mathamatical induction the expression is true for all
Hope this will help you.
