    Tangent line of curve of intersection

    Never mind. By crossing the gradients I found the tangent vector. This makes perfect sense, it was so simple :D :D

    Tangent line of curve of intersection

    I remember why I wanted the vector equation. The only way I can think to find the tangent line is by taking the derivative of a vector equation.

    Tangent line of curve of intersection

    Your right! I was thinking of a vector equation. Then I suppose the parametric equations would look something like: x = -1 +3t², y = 1, z = 3 + t² ? But that still doesn't contain the expected y component, I must be doing something wrong yet.

    Tangent line of curve of intersection

    Homework Statement Find the parametric equations of the line tangent to the curve of intersection of the paraboloid z = x² + y² and the ellipsoid 4x² + y² + z² = 9 at the point ( -1, 1, 2 ). Homework Equations Probable use of the gradient vector (as this is the chapter we are in)...
