Best ResponseYou've already chosen the best response.1LOL @myininaya I thought It was \[\LARGE \lim_{x\to 0}{1\cos x \over \sqrt x}\]

Best ResponseYou've already chosen the best response.0yes. but the question say use limit rule. don't use l'opitall's rule

Best ResponseYou've already chosen the best response.2ok \[\lim_{x \rightarrow 0}\frac{1\cos(x)}{x^2} \cdot \frac{1+\cos(x)}{1+\cos(x)}\] \[\lim_{x \rightarrow 0}\frac{1\cos^2(x)}{x^2(1+\cos(x))}=\lim_{x \rightarrow 0}\frac{\sin^2(x)}{x^2(1+\cos(x))}\] need more help?

Best ResponseYou've already chosen the best response.1you're supposed to know this rule: \[ \lim_{x\to0}{\sin x\over x}= ?\] what should be instead of "?"

Best ResponseYou've already chosen the best response.1so there's nothing to get confused of :) .. @myininaya solved it, you just had to substitute :)
