Evaluate the following limit : lim(x→0) (1 - cos 2mx)/(1 - cos 2nx)

Question

Evaluate the following limit : \(\lim\limits_{\text x \to0}\cfrac{1-cos\,2m\text x}{1-cos\,2n\text x} \)

lim(x→0) (1 - cos 2mx)/(1 - cos 2nx)

Answer 1

  \(\lim\limits_{\text x \to0}\cfrac{1-cos\,2m\text x}{1-cos\,2n\text x} \)

lim(x→0) (1 - cos 2mx)/(1 - cos 2nx)
