Physics I / Problem-Solving: Multivariable Calculus
Practice question · Sort into groups

Sort each theorem: connects which types of integrals?

Groups: Line ↔ Double integral · Surface ↔ Volume integral

Hints
  1. Count the dimensions each theorem works in.
  2. One relates a curve to an area; another a surface to a volume.
Show the answer

Line ↔ Double integral: Green's theorem, Pdx+Qdy=(QxPy)dA\oint P\,dx + Q\,dy = \iint (Q_{x} - P_{y})\,dA, Area via line integral: 12\frac{1}{2}∮(xdy−ydx)

Surface ↔ Volume integral: Divergence theorem, ∬FdS\cdot dS = ∭F\nabla\cdot F dV, Gauss's law in electrostatics

Why

Green's theorem is 2D (line ↔ area); Divergence theorem is 3D (surface ↔ volume).
