Sorry I had to start a new thread here because the latex was just not generating on the other thread, I don't know if it is my browser or something else but I am having a very difficult day with the tex.

anyhow

[tex]

\lim_{x \rightarrow 0} \frac {\sqrt(5x+9)-3}{x} [/tex]

This gives 0/0 off the bat so apply L'H once I get:

[tex]

\lim_{x \rightarrow 0} \frac {(5x+9).5}{2} [/tex]

Which plugs in nicely to give [itex] \frac {45}{2} [/itex]

Did I do that all right?

Hi again can any latex specialists help me. My code definitely says the equation I wrote above is (sqrt(5x+9))-3/x but on my browser there is a red message saying the latex is not valid when I look at the thread and on my preview it is showing me a completely different other tex thing that I wrote two hours ago . I can't seem to avoid this problem, does anyone else see the mix up that I am seeing or is it just my own browser having a hissy fit?
