Before we start, can you just explain how to start me off? I understand the idea of all limits, just a few tricky ones that were assigned for homework. (note: ALL limits are x --> infinity)

lim [tex]^{}\frac{10}{x}[/tex]

lim [tex]\frac{x^{2}+a^{2}}{x^{3}+a^{3}}[/tex]

lim (1 - r[tex]^{x}[/tex]) , |r| < 1

For 10, I'm guessing a = a constant number, so the answer would be zero either way?

**1. The problem statement, all variables and given/known data**lim [tex]^{}\frac{10}{x}[/tex]

lim [tex]\frac{x^{2}+a^{2}}{x^{3}+a^{3}}[/tex]

lim (1 - r[tex]^{x}[/tex]) , |r| < 1

**2. Relevant equations****3. The attempt at a solution**For 10, I'm guessing a = a constant number, so the answer would be zero either way?
