Thread: last question of the night..thank goodness

after hours of trying to make sense of this practice test, im at my last question...another doozy i have no idea on (you may have seen my plethora of other ones that i could not beat)

Use the
M - (delta)definition of limit at infinity to prove the following limits:
lim x>infinity... 3x^2/(5x^2 +1)=3/5
lim x> 1+...1/(x^2 -1)= infinity

Do you know any theorems that you can use? Otherwise, note that . So choosing such that ensures that ..................and done.
