here. Use the same method; just substitute in your numbers.
The example i missed from my lectures is:
Find all points on the ellipsoid 2x^2+3y^2+4z^2=9 at which the tangent plane is parallel to the plane x -2y +3x=5.
How would you do this? Can someone show me please?
Would you be able to finish this problem for me. I can understand it but (x,y,z) must be on the surface so they have to satisfy the original surface equation right?
So I put the scaled values of (x,y,z) into 2x^2+3y^2+4z^2=9
When I went through the problem I got these large and awkward numbers so I'm thinking I messed up somewhere.
