Determine the limits of the following functions as , if they exist.
.
Ive done quite a few of these now, but im stuck on these 4.
edit: while doing my exersices i found a 5th problem that i wasn't sure about:
I think i got the limit as 0 using l'hopitals rule but it got a bit messy and im not sure if i did it right.
For the 1st one, , and as it is obvious , and so the limit is is my method right?
Using l'hopitals rule for the second i got the limit as 1/2.
For the 4th one, i think the limit is 0 because as is that right?
could any1 confirm if my answers are correct?
