# Thread: Field Lines of 3-D vector Functions

1. ## Field Lines of 3-D vector Functions

Hi,

I have been asked to find the field lines of the 3-D vector function:

F(x,y,z) = xyi +(y^2 +1)j + zk

I missed my Math lab due to illness and am finding myself completely stumped on this one. If I recall correctly, the field lines of a 2-D vector function are found from integrating r'(t). I would be very grateful if someone could explain the steps and method used to answer this.
