SUMMARY

The discussion centers on the geometric interpretation of vector components in curvilinear coordinates. Participants clarify that, despite the changing nature of basis vectors in curvilinear coordinates, the components of a vector still represent projections onto these basis vectors at a specific point. This understanding is crucial for integrating vector quantities, as it ensures accurate calculations when the basis varies from point to point.

PREREQUISITES
  • Understanding of vector components and projections
  • Familiarity with curvilinear coordinate systems
  • Basic knowledge of vector calculus
  • Concept of basis vectors in geometry
NEXT STEPS
  • Study the geometric interpretation of curvilinear coordinates
  • Learn about vector integration in curvilinear systems
  • Explore the differences between curvilinear and Cartesian coordinates
  • Investigate applications of curvilinear coordinates in physics
USEFUL FOR

Students and professionals in mathematics, physics, and engineering who seek to deepen their understanding of vector analysis in curvilinear coordinates.

Hi guys, i can not understand something about curvilnear coordinates...from a "geometric" point of view what dose the componentes of the vector mean? in a non-curvilinear coordinates the components are the "projections" on along the bases but in a curvilinear coordinates the directions of the basis vectors changes from point to pint so i can not grasp the geometrical meaning!
Thanks!

The components are still the projection on the basis vectors. In general, it only makes sense to talk about the projection on the basis at the same point as the vector is defined and therefore it is not really an issue that the basis changes from point to point.

Of course, if you want to integrate a vector quantity, it does matter - but can be taken into account fairly easy.
 
Ok...thanks! :)
