1.If you have a vector field F = <-y,x>/(x^2 + y^2)(adsbygoogle = window.adsbygoogle || []).push({});

is that the same thing as saying: F = < -y/(x^2+y^2), x/(x^2 + y^2)>?

That's basically saying that the function 1/(x^2 + y^2) is a scalar.

2.How do you show that vector fields are not conservative for certain values?

Ex: F = <-y,x>/|r|^p show it's not conservative for p = 2.

3. How do you find normal vectors to rounded surfaces given a vector field and the function of the rounded surface? (paraboloids, spheres)
