Homework Help: Cartesian Equation Graph help

  1. Jul 25, 2007 #1
    Cartesian Equation Graph HEELP!!

    1. x=t, y=square root of t, t>0
    cartesian equation: y=root of x

    2. what portion of the graph of the cartesian equation is traced by the parametrized curve?

    3. I don't understand how to find the solution

    When t=0, what are x and y? If t> 0, what are x and y? If t< 0, what are x and y? What part of the graph of [itex]y= \sqrt{x}[/itex] do you lose by dropping the t< 0 part? What part is left (the t> 0 part) ?

    Does the problem itself mention the Cartesian equation [itex]y= \sqrt{x}[/itex]? It would be a better problem if it asked "What portion of the graph of y= x2 is traced by the paramtrized curve?"
