Hi I just need help with several problems. I worked them out and I got an answer but I'm not sure if I did it correctly. Please check my answers.
Find the Limit:
Lim as X -> Positive Infinity of T^2 + 2/ T^3 + ^2 - 1
I don't want to put all my work because I don't know the shorthand to doing it and I'll just put the answer I got. I got 0 as the limit to this problem.
Find the Horizontal and Vertical Asymptotes of each curve:
Y = 1 + X^4/X^2-X^4
I got Horizontal = -1 and Vertical = 1, -1
Same as above
Y = 2e^x/e^x-5
I got Horizontal = 0 and Vertical = -1
Find the limit
Lim x-> positive infinity COSX
I got Lim doesn't exist because COSX is a periodic.
