1. An example of one that I had no clue how to do was #5 on the test. The problem was finding the limit as x approaches negative infinity of f(x)= cos 3x/x.
2. Another example of a limit problem that I had trouble with was #7 on the test. I was pretty confident about the answer I had gotten for it, until I got my test back. The problem was finding the limit as x approaches pi/2 from the positive side of f(x)= tan x.
3. Another problem that was unfortunately also on the test was was the one where we had to find the limit as x approaches -2 of f(x)= 1/x+2
