1. ## vector problem

a particle in the xy-plane at the point (4,2) and moves along the curve y=squrt(x) to the point (0,0) and then returns along the same curve to the point (1,1). Using a single vector-valued function to represent the path of particle over a single interval (for the parameter). Given the interval for the parameter also.

2. Try (t^2,|t|), -2<t<1.

3. ## try to use t^2 and abs(t)

i tried it, but didn't work out for me

It is a correct parameterization, though there are others. Why do you say it doesn't work?

5. ## better explaination

i would like to know the better explaination. Thanks
