I'm trying to display some flow lines for a vector field. The vector field I have is:
What I put into Maple is:
I've tried this with a number of points, but I always get an error message along the lines of:
"Error, (in Student:-VectorCalculus:-FlowLine) cannot determine if this expression is true or false: (2.*(1)(0)-4.)^2+(-2.+4.*(1)(0))^2 < 0.9e-9"
Could someone please shed some light as to what's going wrong for me? I would be very grateful for any help.
