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

well cristo you did a mighty fine job of explaining that for having difficulty. on my next problem i might have to ask for help understanding how to get the portion of the graph that it covers. as for the questions: The initial and terminal points are nonexistant. The cartesian equation...

okay now I've got the answer but how did you get there? how do you know that it covers the whole thing? And is the parametrized equation the same as teh cartesian equation?

okay so now that I've got the cartesian equation for my graph, what is the problem asking when it says what portion of the graph is being traced? as for being in england, I'm no better off. probably worse as it's gorgeous and sunny and i have to do this homework inside all day before it's due...

okay so now that I've simplified down to the cartesian equation (y=x^2), then i substitute x^2=f(x). then how do i find out that there aren't any existing start and end points? sorry it takes so long to reply. at the beach with limited connectivity. I've moved so it should be faster now.

so i set 9t^2 in for y and 3t in for x and then the equation looks like 9t^2=3t(x) and then solve for x so x=3t, but that doesn't leave me with a parametric curve. And then how is that supposed to help me find the starting and end points? sorry i haven't taken math in half a year and i feel...

wait, how do i know that there are no endpoints just by putting 3t, 9t^2 into the cartesian equation?

to get this straight: to get the starting point i'd take negative infinity = 3t, 9t^2 and those would me my initial coordinates. I think my previous teacher said something about the number being so large that it doesn't exist so is that when i put none? and is that the same for the positive...

okay, I'm guessing the initial and terminal points mean where the graph starts and ends, and is that what a cartesian equation is? My book doesn't explain and the examples it gives don't help me grasp what the cartesian equation actually is.

parametric and cartesian equations?? HELP! 1. x = 3t, y = 9t^2, negative infinity<t<positive infinity 2. a) What are the initial and terminal points, if any? Find a Cartesian equation for a curve that contains the parametrized curve. What portion of the grap of the Cartesian equation...
