Felületelemekhez
Felületelemekhez is a term rooted in the concept of a “felületelem” (surface element), a fundamental idea in geometry and physics. A felületelem refers to an infinitesimally small piece of a surface embedded in three-dimensional space. These tiny elements are used to define and compute surface-related quantities such as area, mass distribution, and flux of vector fields.
Mathematically, for a smooth parametric surface r(u,v) with parameters (u,v) in a domain D, the area element
A common example is the sphere of radius R, parameterized by r(θ, φ) = (R sinθ cosφ, R sinθ
Felületelemekhez are widely used in calculations of surface integrals, mass and charge distributions on shells, and
