I'm busy studying for my Calculus A exam tomorrow and I've come across quite a tough question. I know I shouldn't post such localized questions, so if you don't want to answer, you can just push me in the right direction.
I had to use the squeeze theorem to determine: $$\lim_{x\to\infty} \dfrac{\sin(x^2)}{x^3}$$
This was easy enough and I got the limit to equal 0. Now the second part of that question was to use that to determine: $$\lim_{x\to\infty} \dfrac{2x^3 + \sin(x^2)}{1 + x^3}$$
Obvously I can see that I'm going to have to sub in the answer I got from the first limit into this equation, but I can't seem to figure how how to do it.
Any help would really be appreciated! Thanks in advance!
