Answer:
i think its abiu the body brian
Explanation:
Given that y = cos(x) makes up part of the boundary of C, I suspect you mean the given points to be (-π/2, 0) and (π/2, 0).
I also assume the given vector field is
Since has no singularities on C or in its interior, Green's theorem applies:
where D is the interior of C, the region
The integral then reduces to
Since 4x cos(x) is an odd function over the symmetric interval [-π/2, π/2], its contribution to the integral is 0, and the remaining integral is trivial.
$-8.23
