    but hey, we are wrong kingkos, it's not 0, because it's : tanx-x = 0, and it's 0/0 so the result is indeterminate

    use derivative over derivative 3 times(l'Hopital rule) and you'll get 1/3

    No once Is enough remember this standard limit \[\lim_{x \rightarrow 0} \tan(x) /x =1\]

    notsobright it's true, but some proffesors don't alowed to use those basic formulas...just derivatives all the time...at least my doesn't :D
