$\displaystyle

\lim_{x \to 0} {{tan3x}} / {{sin8x}}

$

Can I take the 3/8 out and just multiply it at the end? In any case, I can't find the limit!

I know $\displaystyle

\lim{x /to 0} {{sinx}} / {{x}} = 1

$ but I can't figure out how to get it to work out in this problem...

Also, where can I learn the proper math notation (ie \lim_{x \to 0} {{tan3x}} )?
