    Vacuum adhesion vs hovercraft

    I am doing a senior design project for a mechanical engineering degree. The project I am doing hinges on my teams ability to create a stable platform capable of adhering to a vertical, semi-permeable surface. Presently our greatest challenge is sorting out the mathematical proof of concept for...

    Finding Points of Tangency for Parallel Planes on a Multivariable Surface

    Ok now this I can follow, but I'm pretty sure its what I've been trying. Going by your explanation I would set 4x=-3, 2y=1, and 8z=-2, then solve equation for x y and z to get the first point then multiply every value by some constant to get another point, correct? If so, then that is what I...

    Finding Points of Tangency for Parallel Planes on a Multivariable Surface

    WHAT? I followed you up to setting the ellipsoid equal to 0, then I have no idea what you're talking about. We haven't done lagrange multipliers. We're about half way through Ch. 11 of James Stewart's Calculus: Concepts and Contexts 3. I don't understand how you're establishing a system of...

    Finding Points of Tangency for Parallel Planes on a Multivariable Surface

    Ok, I'm pretty much at whit's end trying to figure this review question out. Apparently my teacher forgot to mention that our book couldn't teach us everything we need to know for our test... Anyhow, the question is as follows, and I'm utterly at a loss as to what the answer is: Find the...

    Graph of r(t) = costi + sintj + costk

    Can someone tell me the general shape of the graph: r(t) = costi + sintj + costk I've been told it's an ellipse, but I thought it was a helix...
