Vector function

  1. Jul 4, 2008 #1
    please help me, I try to do but i can not.

    1. Find a vector function [tex]F(t)[/tex] whose graph is the curve of intersection of
    [tex]z=\sqrt{4-x^2-y^2}[/tex] and [tex]y=x^2[/tex].

    2. Find parametric equations for the line that is tangent to the curve [tex]r(t)=(e^t)i+(sin t)j+\ln(1-t)k[/tex] at t=0.

    3. Find the point on the curve [tex]r(t)=(12sin t)i-(12cos t)j+(5t)k[/tex]
    at a distance [tex]13\pi[/tex] units along the curve from the origin in the direction opposite to the direction of increasing arc length.
