Vedclass · Answer

(D) हम जानते हैं कि $\operatorname{cosec} x - \cot x = \frac{1-\cos x}{\sin x} = 	an(x/2)$.साथ ही,$e^x - e^{-x} \approx 2x$ जब $x 	o 0$.अतः,अंश $	an(x/2) \cdot (e^x - e^{-x}) \approx (x/2) \cdot (2x) = x^2$ है।हर के लिए,$\sqrt{3} - \sqrt{2+\cos x} = \frac{1-\cos x}{\sqrt{3} + \sqrt{2+\cos x}} \approx \frac{x^2/2}{2\sqrt{3}} = \frac{x^2}{4\sqrt{3}}$.इस प्रकार,सीमा का मान $\lim_{x 	o 0} \frac{x^2}{x^2 / (4\sqrt{3})} = 4\sqrt{3}$ है।

$\lim _{x \rightarrow 0} \frac{(\operatorname{cosec} x-\cot x)(e^x-e^{-x})}{\sqrt{3}-\sqrt{2+\cos x}} = $
