There is error in si[t] even after the interpolating function is
obtained. Thanks for fix.

NDSolve[  {si2'[t] == 2, si2[0] == 0,
th2'[t] == Sin[si2[t]]/r2[t], th2[0] == 0, r2'[t] == Cos[si2[t]],
r2[0] == 1}, {si2, r2, th2}, {t, 0, 25}]; r [t_] = r2[t] /. First[%];
th[t_] = th2[t] /. First[%];
(* error -> *)  si[t_] = si2[t] /. First[%];
