Spherical volumes via revolution of polynomials
In considering volumes created by revolving polynomials $y=\beta x^n$ about the y-axis, if we specify $\beta$ so that the curve includes $(0,0)$ and $(a,2a)$ and consider the volumes swept within the ...

Is there a way to modify the solid of revolution integral to allow for solids of increasing and decreasing radius?
I am doing a project on tori as they relate to pool floaties and the volume of a normal torus can be calculated by the solids of revolution integral on a circle, Is there a way to modify the integral ...

On Surfaces of Revolution With Any Two Relations in $\Bbb R^2$ Such that One is the Axis (g) and the Other Revolves (f) defined by z=Rev[f(x),g(x)]:
For the last few years, I have tried a couple times to solve this problem that I came up with. Even though this may seem like a nonsensical idea, there is still a seed of wonder embedded into it.
This ...

Geometric meaning of surface revolution
It's known that the volume of revolution of the function $f(x)$ (assuming it's real, continuous...) is
$$V=\pi\int_a^b f(x)^2dx$$
This can be modelized as if we add together all the infinitesimal ...

How to get the parametric equation of a rotated cylinder (with certain slope)
I have a basic question but I have failed in solving it. I have the equation of a cylinder which is $y^2 + z^2 = r^2$ (centered in the x-axis). The parametric equation (dependent on $L$ and $s$) is $(...

Volume of Revolution but with higher dimensions?
I've learned in my calculus class how a function can be rotated around an axis to create a 3 dimensional shape, and the specific formulae associated with this process. What I'm wondering is whether or ...
