Question

\[\lim_{x \to 0} \frac{e\sin x - 1}{x}\] 

Advertisements

Solution

\[\lim_{x \to 0} \left[ \frac{e\sin x - 1}{x} \right]\]

\[ = \lim_{x \to 0} \left[ \frac{e\sin x - 1}{\sin x} \times \frac{\sin x}{x} \right]\]

 x → 0
∴ sin x → 0

Let y=sin 

x → 0
∴ y → 0 

\[\Rightarrow \lim_{y \to 0} \left( \frac{e^y - 1}{y} \right) \times \lim_{x \to 0} \left( \frac{\sin x}{x} \right)\]
\[ = 1 \times 1\]
