Finding Area of L using Stokes Theorem

Click For Summary
SUMMARY

The discussion centers on using Stokes' Theorem to find the circulation of a vector field F along the line L, which is defined as the intersection of the sphere described by the equation x² + y² + z² = 6 and the plane given by 3x - 4y - z = 0. The intersection is confirmed to be a circle, not an ellipse, as the plane passes through the origin, the center of the sphere. Understanding this geometric relationship is crucial for applying Stokes' Theorem correctly.

PREREQUISITES
  • Understanding of Stokes' Theorem
  • Familiarity with vector fields
  • Knowledge of geometric intersections in three-dimensional space
  • Basic skills in multivariable calculus
NEXT STEPS
  • Study the application of Stokes' Theorem in vector calculus
  • Learn how to compute line integrals over curves
  • Explore the geometric interpretation of intersections between spheres and planes
  • Investigate polar coordinates and their application in calculating areas
USEFUL FOR

Students studying multivariable calculus, particularly those focusing on vector calculus and Stokes' Theorem, as well as educators looking for examples of geometric intersections in three-dimensional space.

Homework Statement



Hey.
I need to find the circulation of F through out the line L.
I know I need to use stokes theorem, the problem is, how do I find the area of L?
I mean, I know the intersection line of the sphere and the plot looks like an ellipse on the XY surface, but how do I find the boundaries? should I switch to polar?

Hi asi123! :smile:

No, it's not an ellipse:

L is the intersection of x2 + y2 + z2 = 6 and 3x - 4y - z = 0,

which is the intersection of a sphere with a plane,

so it's a circle.

And the plane goes through the origin, which is also the centre of the sphere.

Does that help? :smile:
