# Looking for function

1. The problem statement, all variables and given/known data
I need to get a general function in 2 variables f(m,n). You can see a graphicon with charasteristic points:
In the first example m=2 (m is period).

In the next example m=3:

For m=4:

and so on.

The task is to find a general function f(m,n) with these terms:
The function has to be periodic.
The function has to include those blue and red points in each example.
The value of the function has to be f(m,n) =1 ONLY in blue points, and the value of the function has to be f(m,n)=0 ONLY in red points.

The look of the function isn't important as long as it complies with previous terms.

2. Relevant equations
see above

3. The attempt at a solution
try to use absolute, trigonometric functions
