The problem:

Evaluate the integral
[tex]\oint_{c} Fdr[/tex] for [tex]F = (2xy^4)i+(2x^2y^3)j[/tex] on the curve C consisting of the x-axis from x=0 to x=1, the parabola y=1-x^2 up to the y-axis, and the y-axis down to the origin

Here is what I triedF(x,y)=[tex]<2xy^4,2x^2y^3>[/tex][tex]\int\int_{D} =[(2x^2y^3)*\frac{\partial}{\partial x}-(2xy^4)\frac{\partial}{\partial y}] dA[/tex]= [tex]\int_{0}^{1} \int_{1-x^2}^{0} [4xy^3-8xy^3] dy dx[/tex]=1/10

Ok I have redone this problem... multiple times... and now I am getting

-1/10

can someone confirm this for me, I am out of tries on my submission so I need to be sure when I submit this problem
 
alright I solved it nevermind
 
I am so confused by the double integral
