A strange function .

    A strange function.....

    Last night I was faced with a strange function & I couldn't figure out the eqation of the function hence I thought I can get some help from the math experts over here...

    The function passes through these cordinates:

    (3,1) (4,1) (5,2) (6,2) (7,3) (8,3) (9,4) (10,4) ..............
    it's logicallt very simple to predict it's next terms but I still couldn't find the equation....

    I'd be really really glad if someone would help me figure this out...
    Tahnks.

    add two functions. a diagonal ascending one like y = x/2, and an oscilating one like sin. fiddle with coefficients to get it right

    Try using the floor function:

    [tex]\left(x, \lfloor \frac{1}{2}\left( x-1 \right) \rfloor \right)[/tex]

    That is the function might look like this:

    [tex]f: [3,\infty) \rightarrow \Re; x \mapsto \lfloor \frac{1}{2}\left(x-1\right) \rfloor [/tex]
