Evaluate the following limits. If needed, enter INF for \infty and MINF for -\infty.

(a)
\lim_{ x \rightarrow \infty } \frac {10 x + 9 }{ 11 x^2- 3 x + 4 }

(b)
\lim_{ x \rightarrow -\infty } \frac {10 x + 9 }{ 11 x^2- 3 x + 4 }

Is it just me, or is the latex not working?

zarkon · Answer

$$x^2$$

working for me

shayaan_mustafa · Answer

slaaibak · Answer

I mean rukh's post.  Zarkon, yours is working for me.

anonymous · Answer

its been like this for a while now

zarkon · Answer

(a) $$\lim_{ x \rightarrow \infty } \frac {10 x + 9 }{ 11 x^2- 3 x + 4 }$$ (b) $$\lim_{ x \rightarrow -\infty } \frac {10 x + 9 }{ 11 x^2- 3 x + 4 }$$

anonymous · Answer

start with 
"$$"
end with 
"$$"

anonymous · Answer

@Zarkon thanks

anonymous · Answer

$$\lim_{ x \rightarrow \infty } \frac {10 x + 9 }{ 11 x^2- 3 x + 4 }$$

anonymous · Answer

oops what zarkon said

anonymous · Answer

you have to start the latex with 
\[

anonymous · Answer

and end with
 \]

anonymous · Answer

then it should work

zarkon · Answer

or \(

zarkon · Answer

and \)

anonymous · Answer

really?

anonymous · Answer

$\sum$

anonymous · Answer

who knew?

zarkon · Answer

yes...to do inline stuff

if $x^2$ is greater than $x^3$...

zarkon · Answer

doesn't put it on a new line

anonymous · Answer

i think the answer might be 0

anonymous · Answer

what on earth?  
if $x^2$ is greater than $x^3$

zarkon · Answer

it is

anonymous · Answer

sorry  yes, the answer is zero to both since degree of numerator is smaller than degree of denominator

anonymous · Answer

thanks :)

anonymous · Answer

i learn something new every day
does require that extra "shift" though

zarkon · Answer

if you are doing inline latex you can also do the following ...since inline doesn't look as good at not inline

$\sum_{n=1}^{\infty}a_n$ vs $\displaystyle\sum_{n=1}^{\infty}a_n$ 

\sum_{n=1}^{\infty}a_n 
vs
 \displaystyle\sum_{n=1}^{\infty}a_n

anonymous · Answer

i will definitely use it because there are times when it is annoying to have to start a new line

anonymous · Answer

i noticed that with actual latex documents using $ instead of \(

zarkon · Answer

yes...same thing


also $$ for \[

anonymous · Answer

can you use \( instead of $ in a document?

zarkon · Answer

yes

anonymous · Answer

i think i remember reading that 
$ was actually a hack and the preferred method is 
\[
but i could be wrong

zarkon · Answer

$ is for \(

$$ is for \[

anonymous · Answer

ah i see. all this time i have been using $ and \[ but never the other two
thanks!

zarkon · Answer

I used $ for years...just started to use \( full time now

anonymous · Answer

more key strokes

zarkon · Answer

np  :)

zarkon · Answer

I think it looks nicer though ;)

anonymous · Answer

i think i will post this in latex practicing
