Evaluate the line integral in Stokes? Theorem to evaluate the surface integral integrate S ( x F) n dS. Assume that n is in the
positive z-direction. F=(x+y,y+z,z+x); Sis the tilted disk enclosed by r(t)=(cost,4 sin t root 5 cost). Integrate s ( * F). n ds= (Type an exact answer. using pi as needed)
