So we were learning about 2 dimensional domain functions today, and my prof put up a limit. he did some work and then did something I was a bit stumped on for a while: . Isn't this indeterminate? Would it be 0 because y^2 is not ACTUALLY 0, but simple a number really close to 0 and then numerator is fixed at 0, so 0 divided by any number close to 0 is still 0. Am I right?

P.S. How do you get to go under the word "limit" rather than next to it?
