Here's the question you clicked on:
math_proof
line integral over the vector field
\[F= \frac{ <x,y> }{ (x^2+y^2)^{3/2} } \] on the line segment from (2,2) to (10,10)
i found r(t)= <2+8t, 2+8t> so then i have trouble calculating F
i got the answer 2/5 is it right?
Does the question mean \[F=(\frac{x}{(x^2+y^2)^{1.5}},\frac{y}{(x^2+y^2)^{1.5}})\]?
