Hi, I want to know if there's a general method of changing variables of a function and reduce the original number of variables (which is what parametrization is, right?).
For example one parametrization for the function whose graphic is a circunference is x = Rcos(t) and y = Rsin(t). But is there any method to find that parametrization algorithmically?
