(1 point) let f(x, y)=−yi+xjx2+y2 and let c be the circle r(t)=(cost)i+(sint)j, 0≤t≤2π. a. compute ∂q∂x (-x^2+y^2)/(x^2+y^2)^2 note: your answer should be an expression of x and y; e. g. "3xy - y" b. compute ∂p∂y -[(x^2-y^2)/(x^2+y^2)^2] note: your answer should be an expression of x and y; e. g. "3xy - y" c. compute ∫cf⋅dr note: your answer should be a number d. is f conservative? type y if yes, type n if no.
