1. The problem statement, all variables and given/known data Find the distance from the paraboloid z = X2 + 2Y2 to the plane 2X + 8Y + Z = -8. 2. Relevant equations The partial derivatives with respect to X, And Y for the paraboloid. 3. The attempt at a solution My professor said we need to find the point where the tangent plane of the paraboloid is parallel to the plane. I can take the X, and Y partial derivatives, but then I do not know what to do.
