Hi,
You can, for example, compute the function values and store the values
in a histogram. Example
root > TF1 *f1 = new TF1("f1","sin(x)/x",0,10);
root > TH1F h("h","",100,0,10);
root > h.Eval(f1);
but, in general, with Root, this is not necessary. You can directly
evaluate the function value, example
root > f1->Eval(5);
