62{x} has period 1.
at x->-1/2 it has value -∞
at x->+1/2 it has value ∞
The first part is finite. so that will not interfere... so the periodicity is 1
I still think that graph is a better way for this one
62any other method will still require some analysis..
which, to me will be essentially the graph approach somewhere in the backside of the calculations even if i did not write it explicitly..
