How to set ranges for parameters(TMinuit) with conditions


In order to use TMinuit, I need to set ranges for parameters through mnparm(i, name_i, ini_i, lng_i, min_i, max_i, ierflg);

If I want to fit the function f(x)=p0+p1cos(p2x+p3), with 0.001<f(x)<0.1 and 0.001<p2<0.1, how should I set proper “lower and upper physical parameter limits” of p0 and p1 for mnparm?
