Grad, div, curl of F

So, I am sitting here all alone in my room studying for like the 7 straight hour for my calculus 3 test later this evening, and i have gotten a little bored. Everyone has already left for Thanksgiving break but i will be here until tomorrow morning... Oh well. But i am going over my notes for Calc and i noticed some very funny, disturbing, and quite weird comments i have written down and i want to share them. So here goes. Keep in mind all of these things were said by my professor.

• "The use of r, theta instead of x,y may be advantageous when the integrand (aka the function) and/or the boundary of R are/is most naturally expressed in terms of r, theta." -- Ya sounds fun right?
• He goes through an entire problem then stops after he gets the answer and says "but thats wrong..." --uh... so you showed us what not to do??
• My professor talking about finding the surface area, "this looks horrible and in calculations it is often going to be horrible." -- GREAT!!
• Now he's talking about going from double to triple integrals.... "let's make things worse," after a short laugh from the class... "truthfully." -- doesn't this class sound fun?
• "Line integrals" he does an example, "More line integrals" does another example, "Yet more line integrals" does yet another example.
• "Anticlockwise, or as you Americans say 'counterclockwise'".
• "Spherical polars are just making things worse, so, obviously, choose a different method."

So, basically, this class is a lot of fun.... but good news is after this test i can relax and see my family tomorrow for Thanksgiving break :)

Love ya!
