    Find the equation of the plane that satisfies the stated conditions.

    Find the equation of the plane (if you dare) that is tangent to the following spheres: sphere 1: r=2 center P(2,2,2) sphere 2: r=3 center Q(3,4,5) Ok, I know that the plane will be parallel to the vector PQ = <1,2,3> For the equation of a plane I need a normal vector, and a point...

    Intersection of a paraboloid and a plane

    A similar question - but more variables are present: Find the intersection of the plane 2x-y-3z=15 and the paraboloid 3z=(x^2)/16 + (y^2)/9 I was unable to use the above method because of the "z" variable in the plane equation. Can I still use the above method? Or is something else...
