Please answer! Find parametric equations for the curve y = x + 1, x ≥ 0, by using as parameter the distance of the point (x,y) from the origin.

Question

loser66 · Answer

to me, I just do something like  
                 x = t 
                 y = 1 +t
that's it

That would be the answer?

You also need the condition in the parametric answer.

loser66 · Answer

ok, so it t>=0?

e.mccormick · Answer

Yah, and perhaps $\in\mathbb{R}$

e.mccormick · Answer

Let $x=t,~ y=t+1;t\in\mathbb{R}\ge 0$

e.mccormick · Answer

I think that is a proper answer.  Sometimes they want { } around parametic answers as well.  Setbuilder notation.

e.mccormick · Answer

Parametric from Parameter and I have no clue what.  Probably just an ending denoting action or an item.  Para- beside, -meter measure.  So it it the measure of things near together.  A set.  That is the language of it, which kind of explains why they use this odd term to mean something as simple as "build a set for this with all the rules needed."
