Homework Help: Another Representing a curve with a vector valued function

  1. Sep 21, 2010 #1
    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.

    Answers I got

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

    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
