yeah but have u seen the mathematika's defn,i have a dbt on that.Y the defn for frac(x) differs.

http://mathworld.wolfram.com/FractionalPart.html

Look at this link it gives u a different defn of frac(x)

look ,things get simplified if u write {x}=x-[x]

as y=x(x-[x])
=x²-x[x]

which if taken in intervals (for example 0<x<1 and so on)....reduces to a quadratic equation....which can be drawn easily[1][1]

@msp I don't see any fault in his graph

for (-1,0) it will be y=x(x+1) and y cannot be positive and hence give the result as shown
