a) lim (as x goes to infinity) f(x)
b) lim (as x goes to pi from the left) ln(f(x))
I got the answers, but I'd really like the simplest explanation possible as I am trying to figure out "how else" the professor can ask this on the test. Also, for part b, his explanation was that approaching zero with a very small, finite # is DNE. how does ln(sinx/x) equal that?
Thanks for any help!
