Hey guys,

How do I prove that (1/nx) --> 0 pointwise but not uniformly on (0,1) as n tends to infinity.

thanks in advance, I appreciate your help.

I think that's just a formatting code that's no longer used - nothing mathematical about it. Here's CB's reply without the "br" formatting codes:

On and any ,

which proves pointwise convergence.

For uniform convergence for we need to find an N such that for all :

But for where which contradicts what would have to be true for uniform convergence to hold.

By the way, why did you resurrect this 4-year-old thread?
