yeah, that is a typo on my part. it's supposed to be x -> pi/6. but the rest is the way it is on the test.Originally posted by Cshot

>> Cshot, I'm not sure because you would end up with .366/0, and that isn't possible.

You're right that .366/0 is undefined. But this is a limit problem. As x->pi/6, the limit goes to infinity.

And yea, I was just joking about the h->pi/6 part

one related question: when the limit of a function is plus or minus infinity, isn't the answer still undefined? i thought that the use of infinity here was just showing one type of undefined answer, acting as notation and not as a number.
