Graphing a Shifted Elliptic Paraboloid in 3D

▶️ Watch on 3Speak


In this video I graph a shifted and horizontal elliptic paraboloid, which is a quadric surface that opens up along parabolic traces while the cross-section has elliptical traces. This is the same shape as in my earlier video but this time the elliptic paraboloid is shifted so that the origin is (3, 1, 0) and opens horizontally parallel to the y-axis.

    Interesting stuff
    I did not conduct a long study in Math.
    It is impressive to use this formula to resolve industrial problems in our daily life.
    Peace

    Just discovered your videos, they seem really nice!
    Will have to dive deeper into them to understand them more deeply.
    Thanks for sharing!
