Cool notes, anon. It helps. Also, I would appreciate if you have notes on proving a limit exists for f(x) and f(x,y) with all the delta epsilon stuff?

My TA and professor insist I use the method in my pic related. Where (x,y)=(1/n,1/n). Although, it would obviously be of benefit knowing a variety of techniques. When 1/n may not work.

Also if: lim x->a f(x)=L where L means limit?
Then I presume if you replace L with l0 it would also mean the same thing. I am just trying to clarify what these letters mean in my textbook.
