    start by estimating the integral by a riemann sum. it all depends on knowing what dot products measure. (hint: the more parallel two vectors are, the greater their dot product.)

    I would suggest you start trying to apply calculus instead of posting pictures.

    to start off that im not bluffing, the first two graphics are negative because of the parallel circulation creating a negative flux

    2a/b are both answers are equal to zero. I used the potential function out that f=xy and apply the f(Q)-f(P) which ends up with zero answer. But I need to find the answer using different formulas. SO, can anyone shows me other formulas
