I really need help for my homework.My professor gave me 2 questions about vector calculus, but I can not understand it.
thanks for your help
1)Suppose the one dimensional field A=Kx.ax exist in a region. Illustrate the validity of Gaussian theorem by evaluating its volume and surface integrals inside and the rectangular parallelepiped bounded by surface: x=1,x=4,y=2,y=-2,z=0,z=3
2)Verify the stoke’s theorem, where C is the triangle with vertices: (1,0,0), (0,2,0), and (0,0,3), oriented by the order in which the points are given, and F(x,y,z)=(yz,-xz,xy)
