$\sqrt{2}$

Vedclass · Answer

(C) हमारे पास $\mathop {\lim }\limits_{x 	o 0} \frac{{\sqrt {1 - \cos {x^2}} }}{{1 - \cos x}} = \mathop {\lim }\limits_{x 	o 0} \frac{{\sqrt {2 \sin^2(x^2/2)} }}{{2 \sin^2(x/2)}}$ है।चूंकि $x 	o 0$ के लिए,$\sin(x^2/2) > 0$,इसलिए:$= \mathop {\lim }\limits_{x 	o 0} \frac{{\sqrt{2} \sin(x^2/2)}}{{2 \sin^2(x/2)}} = \frac{1}{\sqrt{2}} \mathop {\lim }\limits_{x 	o 0} \frac{\sin(x^2/2)}{\sin^2(x/2)}$.$(x^2/2)$ और $(x/2)^2$ से गुणा और भाग करने पर:$= \frac{1}{\sqrt{2}} \mathop {\lim }\limits_{x 	o 0} \left( \frac{\sin(x^2/2)}{x^2/2} \cdot \frac{x^2/2}{(\sin(x/2)/(x/2))^2 \cdot (x^2/4)} ight)$.$= \frac{1}{\sqrt{2}} \cdot \frac{1/2}{1/4} \cdot 1 = \sqrt{2}$.

$\mathop {\lim }\limits_{x \to 0} \frac{{\sqrt {1 - \cos {x^2}} }}{{1 - \cos x}}$ का मान है
