Evaluate the line integral F dr, where C is given by the vector function r(t). F(x, y) = xy + 6y j r(t) = 14 tj, 0 t 1 Need Help? Read It Watch It Master It Submit Answer Determine whether or not F is a conservative vector field. If it is, find a function f such that F = Vf. (If the vector field is not conservative, enter DNE.) F(x, y) = (2x-2y) + (-2x + 10y - 9) j f(x, y) =DNE Need Help? Read It Watch It Master It Evaluate the line integral F dr, where C is given by the vector function r(t).
