Question

Calc III:
Sketch the vector of the field F by drawing a diagram. F(x,y)=-(1/2)i+(y-x)j

Answer 1

But how exactly did you do that?

Answer 2

Are you still here?

Answer 3

For each point as starting point of a vector say (1,0), you draw the vector
{1/2,0-1}={1/2,-1}.
You do this at several points. I did my graph with a computer. But the idea is simple.

Answer 4

Ah,but when the equation equals 1/2 At (0,0) how come the vector isn't bigger?
