Question

(2x+5)/(x^3-1) 
Find the limit of x as x approaches infinity
Must use only algebraic methods...

anonymous · Answer

devide everything by x and take the limit, keeping in mind that $a/\infty=0$, where a is any number

anonymous · Answer

Im sorry but I cant seem to figure out how to write the equation as divided by x. Sorry for my inability to preform simple math ;)

Mate?

anonymous · Answer

I'm pretty sure this is the same problem as the last one. I did if algebraically after.

but here it is in one step.

$$\frac{ 2x+5 }{ x^3 - 1 } = \frac{ 2+ \frac{ 5 }{ x } }{ x^2 - \frac{ 1 }{ x } }$$

anonymous · Answer

Haha it was, but I couldn't seem to decode the algebraic method you used to work on other problems so I had to ask it again

anonymous · Answer

hehe. do you see it now? every term is simply divided individually by x

anonymous · Answer

Well when you put it that way, it makes me seem like an idiot; So I am going to just say I knew that originally and that I didn't just realize that....
