Hi, Plot[#^2/(# + 1)^2 &[x], {x, 0, 4}] ?? or f[x_] := x^2/(x + 1)^2 Plot[f[x], {x, 0, 4}] or Plot[x^2/(x + 1)^2, {x, 0, 4}] Regards Jens Serg wrote: > i think i've asked this before. anyway, i am new in mathematica and i want how can I create the graphic of an exact function the same as I do for Sin[]. > > for example f(x)=x^2/(x+1)^2 > can anyone help? >
