could someone explain to me what exactly parametrization of a function in more than parameter means? so i know that for f(x)=x^2 there are two parameters, x x^2 but how does that lead to a circle being Sin(x) Cos(y)? what does this actually mean?? i.e. in the first example, i get it, in the second, i really don't. is there a general way to take a parametrization and turn it into a "regular" function?
