Question

line integrals anyone?

Answer 1

calculate line integral of the vector feild: f(x,y) =\[(x^{2} -2xy)i + (y ^{2}-2xy)j\]

Answer 2

from -1,1 to 1,1 along the parabola y=x^2

Answer 3

what i did was parametrize the equation. x=t and y=t^2
then i differentiated it. {a'(t)
plugged t in f(x,y) to get f(a(t))
then integral f(a(t)).a't dt
BUT i got wrong answer! =/

Answer 4

{a'(t) ye kis cheex ki notation hy ?
