प्रश्न

\[\lim_{x \to 0} \frac{\tan mx}{\tan nx}\] 

Advertisements

उत्तर

\[\lim_{x \to 0} \left[ \frac{\tan mx}{\tan nx} \right]\] 

\[\Rightarrow \lim_{x \to 0} \left( \frac{\tan mx}{mx} \times \frac{mx}{nx} \times \frac{nx}{\tan nx} \right)\]
\[ \Rightarrow \lim_{x \to 0} \left( \frac{\tan mx}{mx} \times \frac{mx}{\frac{\tan nx}{nx}} \times nx \right)\]
\[ \Rightarrow \frac{m}{n} \left[ \because \lim_{x \to 0} \frac{\tan x}{x} = 1 \right]\]
