intuitive understanding of polygon area calculation by using determinant:

**Goal**

- Understand
*Green's theorem*- [o] start from definition of
*line integral*- those two facts matters
- uniqueness of line integral
- orientation fixed

- those two facts matters
- [o] explicitly expand the theorem equation to remove confusion
- [o] intuitively understand with area calculation case
- [x] look for the general case proof

- [o] start from definition of
- [o] Green't theorem's application for
*area calculation*with simple case - [o]
*Planimeter*explained via Green's theorem - [o] Verteces based polygon area calculation equation explained following above
