Evaluate the following limit :\(\lim\limits_{\text x \to0}\cfrac{1- cos\,5\text x}{1-cos 6\text x}\)lim(x→0) (1 - cos 5x)/(1- cos 6x)

Answer»

\(\lim\limits_{\text x \to0}\cfrac{1- cos\,5\text x}{1-cos 6\text x}\)

Hence,\(\lim\limits_{\text x \to0}\cfrac{1- cos\,5\text x}{1-cos 6\text x}\)=\(\cfrac{25}{36}\)
