How to Use Green's Theorem: Example with Integral((y - x)dx + (2x - y)dy), y - x, y = x^2 - 2x

TL;DR

Using Green's Theorem to evaluate an integral given a region's boundary.

Transcript

hi in this problem we're going to use green's theorem to evaluate this integral so here c is the boundary of the region between the lines y equals x and y equals x squared minus 2x let's go ahead and work through this solution i'm going to start by writing down the formula so it tells us that if we're integrating along c and we have m dx plus n d y...
