\(\lim _{x \rightarrow 0} \frac{x \tan 2 x-2 x \tan x}{(1-\cos 3 x)(\operatorname{cosec} x-\cot x)^2}=\)
- A \(\frac{4}{9}\)
- B \(\frac{8}{9}\)
- C \(\frac{16}{9}\)
- D \(\frac{32}{9}\)
Answer & Solution
Correct Answer
(C) \(\frac{16}{9}\)
Step-by-step Solution
Detailed explanation
\( \lim _{x \rightarrow 0} \frac{x \tan 2 x-2 x \tan x}{(1-\cos 3 x)(\operatorname{cosec} x-\cot x)^2} \) \( = \lim _{x \rightarrow 0} \frac{x(\tan 2 x-2 \tan x)}{(1-\cos 3 x)\left(\frac{1-\cos x}{\sin x}\right)^2} \)…
