This document contains a group project submission on multi-variable calculus topics to Sir Asad Ijaz. It lists the group members and covers line integrals, the fundamental theorem of line integrals, exact differential forms, and Green's theorem in the plane. Green's theorem relates the line integral around a closed curve to a double integral over the interior region and has two forms - the flux-divergence form and the circulation-curl form. The document provides definitions, examples, and exercises for understanding these concepts.
