$\mathop {\lim }\limits_{x \to 0} \frac{\sin x}{x}$ ની કિંમત શું થાય?

$\mathop {\lim }\limits_{x \to 0} \frac{{2{{\sin }^2}3x}}{{{x^2}}} = $

$\lim _{x}$ ${\rightarrow 0} \left( \left( \frac{1-\cos ^2(3 x)}{\cos ^3(4 x)} \right) \left( \frac{\sin ^3(4 x)}{(\log _e(2 x+1))^5} \right) \right)$ ની કિંમત $.........$ છે.

$\lim _{x \rightarrow 1}(1-x) \tan \left(\frac{\pi}{2} x\right) = $

$\lim _{x \rightarrow 0} \frac{\cos ax - \cos bx}{x^{2}}$ ની કિંમત શોધો.

$\lim _{x \rightarrow 0} \frac{\sin ^{2}\left(\pi \cos ^{4} x\right)}{x^{4}}$ ની કિંમત શોધો.
