this is a discrete function

anonymous · Answer

the answer seems to be in terms of p

I don't know if I can help
I thought.....since x is real and [] will only output integers, that it is then not differentiable unless constant

anonymous · Answer

Consider the simplified problem of finding the points/intervals where 

$$[\sin (x)]$$
is differentiable

anonymous · Answer

Where {sin(x)] is differentiable isnt too bad. It looks like this:|dw:1375771181932:dw|
