  1. Particle on a hemisphere - lagrange - Mathematics Stack Exchange

    A particle of mass $m$ is on top of a frictionless hemisphere centered at the origin with radius $R$. It starts sliding down the hemisphere. Set up the Lagrange equations of the first kind and dete...

  2. multivariable calculus - Parameterizing a hemisphere: Why are these …

    Graphing it out, it looks like a normal hemisphere cut in half at the Y axis. When we learned how to infer the values of φ and θ for a parameterized sphere in class, we were told that generally φ is the …

  3. calculus - Parameterizing the upper hemisphere of a sphere with an ...

    Parameterizing the upper hemisphere of a sphere with an upward pointing normal Ask Question Asked 14 years, 7 months ago Modified 14 years, 7 months ago

  4. bottom half of a sphere - Mathematics Stack Exchange

    if a sphere is of the equation $r^2 = x^2 + y ^2 +z ^2$ and we want to find a hemisphere does that just involve setting a limit to be half of the radius ? For example ...

  5. Stokes's theorem outer unit normal for a hemisphere

    Nov 7, 2015 · I believe there are three outer normal vectors, but the equation you wrote down is for Green's theorem, and it's not clear what you want to do.

  6. Equation for curves running along a hemisphere of arbitrary size

    Aug 17, 2018 · Is there an equation that could represent any latitudinal line that lies along the surface of the hemisphere? I want to be able to have an equation that could describe the curve that runs along …

  7. Why is this parametrization of a hemisphere wrong?

    Sep 5, 2020 · A hemisphere is obtained by restricting $\theta$ to $ [0,\frac {\pi} {2}]$. Here is a vizualization from Wikipedia: Coming up with this quickly is not something you're supposed to do in …

  8. Normal vector for a surface: explicit vs implicit formula

    Dec 20, 2013 · But as I understand Stokes' theorem which relates a surface integral to the line integral of its boundary, the normal vector of the surface to integrate must be a unit vector, but the textbook …

  9. integration - Centre of mass of a uniform hemispherical shell ...

    Dec 7, 2024 · I'm attempting to derive the centre of mass of a uniform hemispherical shell by considering it as a series of circular strips of width dx. Like a solid of revolution but with circular strips rather...

  10. Equation of non-axis-aligned ellipse resulting from hemisphere ...

    Sep 29, 2019 · Equation of non-axis-aligned ellipse resulting from hemisphere projected circle Ask Question Asked 5 years, 11 months ago Modified 5 years, 11 months ago
