Parametric Eq. Query

Hopefully this forum is okay to make the following inquiry (or in general): Anyone know of a parametric representation of z = (x^2 + y^2) ^ (1/2)? I'd like to apply the 2 variable chain rule to diff. it in terms of t & need a push in the right direction.

Thanks in advance for any insightful replies specifically related to the question.

bicuspid curve? is t =Time.not sure what your trying to do

Nah, not a bicuspid curve.

I should maybe be more explicit with my question and omit what my intent is: Anyone know a parametric representation of z = (x^2 + y^2) ^ (1/2)?

Thank for the reply though

This is one equation but it has 2 unknowns. Without a single valued function establishing the relationship between X and Y, an infinite number of (X,Y) pair solutions exist for every value of Z. Without this second equation it is impossible to rewrite it in terms of some parametric variable t.

IMO

Heh, heh. The duck and Ma Deuce is an image I'll not soon forget. Good stuff

Regarding your question, are you looking to convert this equation from Cartesian to polar coordinates?
