Parametric Equations for Circle and Spiral Curves

[mattb8818]

I was wondering if someone could give me an overview of what they are and how to get them. Thanks

That is much too general a question. There are even many differents kinds of "parametric representation".

Ok, It is for a multivariable calcul us class. Could I give a few examples and maybe you could explain them to me?

Find parametric rep. of Circle y^2 + 4y + z^2 = 5, x = 3

what curves are represented?

2 + r cos 4t, 6 + r sin 4t, 2t
