Spherical romashishka in vacuo. Bashny.Net

Continuing: mat-tits; Klenobula

Today, dear YaPovtsy, I'll show how to use Mathcad and Tuyev Hoochi unnecessary, but cognitive formulas make romashishku spherical vacuum. Why spherical? Because will is involved through the parameterisation functions mainly spherical coordinates (azimuth, zenith distance), but a little more and cylindrical. Why vacuum? Yes, because it's just a mathematical abstraction.

Constructive criticism, boobs, Romer, toads, and other stimulating materials is welcomed to heighten interest in the maintenance and promotion of the material.
It will be 10 images.

I was in one of the posts mat art delivered a statement that such a schedule mat-boobs is impossible, meaning that one abscissa value chart must match one ordinate value graph related through the function y (x).

Due to the parameterization function can almost everything!
Example: The Lissajous
F (x (t), y (t)) = (x, y), where (x, y) - coordinates points.
x (t) = sin (m * t)
y (t) = sin (n * t + const)
Then, in a classic expression y (x) = y (x (t * n / m + const))

But I got carried away, it's time to start romashishke spherical vacuum. Just note that all started when I opened the manual / HELP and on it built a sphere, and then it started ... :)
Threat Vkurivayte manual (RTFM), because it is instructive.
