Homework Statement


For \mathbb{R}^{3} find the integral curves of the vector field B = xy\frac{\partial }{\partial x} - y^{2}\frac{\partial }{\partial y}.

Homework Equations


The Attempt at a Solution


I am having a hard time understand just how to set up the differential equations in order to solve for the family of integral curves. Is it:
\frac{\mathrm{d} x}{\mathrm{d} t} = xy
\frac{\mathrm{d} y}{\mathrm{d} t} = -y^{2}
\frac{\mathrm{d} z}{\mathrm{d} t} = 0?

I'm pretty rusty on vector calculus, but this doesn't look like a vector field to me. Are you sure this is the exact wording of the problem?

Yes sir it was. Its the only problem in Appendix B (Diffeomorphisms and Lie Derivatives) of Spacetime and Geometry - S. Carroll.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
