Another ....Representing a curve with a vector valued function

1. The problem statement, all variables and given/known data

Find the vector-valued function that represents the curve of intersection between the following surfaces:

1) z=y6 , x=z1/3

2) z=ex , x=y4

2. Relevant equations

3. The attempt at a solution

Attached my work

I don't have any answers for these so I'm hoping someone can check my work? It seemed almost too easy.

1) r(t)=ti+t1/2j+t3k
2) r(t)=ti+t1/4j+etk

Re: Another ....Representing a curve with a vector valued function

first one looks reasonable, but you might want to put some constraints on t, think about the allowable values of z for the first surface
