comment Evaluating $\oint_C (\arctan{y} - 5y)dx + \left(\frac{x}{1+y^2} + 2x\right)dy$
Then I can just use that?

comment What does it mean to be divergence thorem applicable?
@BradyTrainor when this example problem, my teacher was like first you need to check if they are piecewise smooth and check if check if $\vec{F}(x,y,z)$ is continuously differentiable. He then said since it follows all those conditions, the divergence theorem can be applied. He didn't show how he recognized that they follow those conditions. Couldn't someone tell me how he did?

comment How do you use the gradient to find $n$?
$$z = \sqrt{1 - x^2 - y^2}$$ oh so does $$sqrt(1 - x^2 - y^2)$$ always represent the radius?

comment How do you use the gradient to find $n$?
@hyg17 what do you mean the norm of $\overrightarrow{N}$ is not always 1? Isn't $\overrightarrow{N}$ = <2x,2y,2z>? How can you tell by the question if the norm of $\overrightarrow{N}$ is 1?

comment How do you use the gradient to find $n$?
but how does sqrt(x^2 + y^2 + z^2) in the denominator become 1 all of a sudden and you are left with <x,y,z>?
