We want to verify green's theorem for this integral.
00:04
So first of all, we want to, let's call our three segments here.
00:12
One, two, and three.
00:18
So this integral is integral over one plus the integral over two, plus the integral over three.
00:32
So for one, we have x equals constant.
00:38
So d x is zero.
00:43
This one here is d .y equals zero.
00:47
Okay, so this one.
00:51
So number one, integrates on y from 1 to 0, y, d, y, d, y, and then this one has d, y, equals 0, so it actually is x, d x, x, from 0 to 1.
01:16
And then we have to integrate on three, the circle, right? so for the circle, i'm going to parameterize this from x is cosine t, y is sine t...
