2-22 Divergence Theorem Flux Through a Cylinder

P.2-22 For a vector function A = a,r 2 + a=2:::. verify the divergence theorem for the circular cylindrical region enclosed by r = 5, ::: = O. and z = 4.

skip to 6:22 to start the problem solution with no background info, also 12:52 I just did that with the bottom bounds because they were all zero - do your math more systematically for the integral (like later examples) or you might get in trouble. I just skipped because it canceled.

Best explanation of this that i have come across. I like how you explain the differential surface areas instead of telling us them unlike my professor. Amazing job, Thank you so much.

Great video! Helped me remember all that calc 3 stuff.

I was struggling with my assignment and this video helped me so much. Thank you!

Amazing explanation, my professor went over this problem in class but he kept making mistakes and had to go back a couple of times to correct himself. Wish you could teach my class lol

Thank you your explanation was perfect

Hi, Surface element ds has a third equation in the phi direction, I was confused why it wasnt used here ?? I always get confused which equation to use when using ds

Hi how come we don't have to normalize the normal vector?
