Question

in line integral how can we change the vector field(x,y) into parametrized(x(t),y(t)) form, since the parametrization is only given for the curve as x=f(t);y=f(t) and not the vector field

Answer 1

yah!! see you can should see it this way, as we change "t" x and y both change and further x and y give a specific point on the graph of x-y now as we change "t" we inturn are changing values of x,y which further is giving us the direction and magnitude of force at that point.in short its just that (field is a function of x,y and xx and y are inturn functions of t... hope that this solved ur quirey if not plzzz ask wat u didnt understand exactly

Answer 2

sorry,i didnt understand ur answer
