$\mathop {\lim }\limits_{x \to 0} \frac{{1 - \cos x}}{x} = $

$\mathop {\lim }\limits_{a \to 0} \frac{{\sin a - \tan a}}{{{{\sin }^3}a}}$ ની કિંમત શું થશે?

જો $x = \log_e \left( \cot \left( \frac{\pi}{4} + \theta \right) \right)$ હોય,તો $\lim_{\theta \rightarrow 0} \frac{\theta}{(\sinh x)(\cosh x)} = $

$\mathop {\lim }\limits_{x \to 0} \frac{{\sin {x^\circ}}}{x} = $

$\mathop {\lim }\limits_{x \to 1} (1 - x)\tan \left( {\frac{{\pi x}}{2}} \right) = $

લક્ષની કિંમત શોધો: $\lim _{x \rightarrow 0} \frac{\tan ^2(\pi \sec ^4 x)}{\pi^2 x^4}$
