Using only trigonometric functions and a single instance of the number zero, derive a formula to calculate any positive integer n.

Bumping this thread.
 
Does that include the argument the function takes?
 
If not, f(x) = 0 + tan(tan-1(x)) where x is assigned the desired integer n.
Or even simpler f(x) = 0 + x. No trig needed.
I know that I'm missing something.

Could you give an example as to form, one that is not the answer?.

this one breaks the op because it uses "floor command" and also sneaks in an implied (-1) but since you asked for a bad example, here you go:

 

(floor(arccos(-cos(0))))! using the main branch of the arccos [0,pi].
