Let's examine Stokes' Theorem, which extends Green's Theorem to regions not confined to the 𝑥𝑦-plane but floating (as surfaces) in ℝ3. This theorem connects the circulation of a vector field F(x,y,z) around a surface's boundary to the integral of the field's curl across the surface (measuring rotation across S). (Multivariable Calculus Unit 7 Lecture 4) • Stokes' Theorem states that the circulation of a vector field 𝐹⃗ around a surface 𝑆's boundary is equal to the integral of the curl of 𝐹⃗ across 𝑆: ∮ 𝐹⃗ ⋅𝑑𝑟⃗ =∬ ∇×𝐹⃗ ⋅𝑑𝑆⃗, where the domain on the left is the boundary C of S, and the domain on the right is S itself. We do an example of both sides of this equality in the video. • Stokes' Theorem provides a powerful tool for analyzing vector fields in three-dimensional space, especially for surfaces with complex geometries. Understanding the theorem's application requires careful attention to the orientation of surfaces and their boundaries, following the right-hand rule. The theorem beautifully connects the concepts of circulation and curl, offering insights into the behavior of vector fields across surfaces. • Stokes' Theorem applies to surfaces in ℝ3, not limited to the 𝑥𝑦-plane. (A flattened surface in the 𝑥𝑦-plane brings us to Green's Theorem as a special case of Stokes'.) • It requires an orientation of surfaces and boundary curves consistent with the right-hand rule. Correct orientation ensures that the thumb (representing the normal vector) points in the direction of the surface's outward vector, with the fingers (representing the boundary curve) following the direction of the curve's motion. • #calculus #multivariablecalculus #mathematics #stokes #vectorcalculus #iitjammathematics #calculus3
