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

ધારો કે $f : R \rightarrow R$ એક વિકલનીય વિધેય છે જેથી $f \left(\frac{\pi}{4}\right)=\sqrt{2}$,$f \left(\frac{\pi}{2}\right)=0$ અને $f^{\prime}\left(\frac{\pi}{2}\right)=1$ થાય. જો $g(x)=\int\limits_{x}^{\pi / 4}\left(f^{\prime}(t) \sec t+\tan t \sec t f(t)\right) d t$ એ $x \in\left[\frac{\pi}{4}, \frac{\pi}{2}\right)$ માટે હોય,તો $\lim\limits _{ x \rightarrow\left(\frac{\pi}{2}\right)^{-}} g ( x )$ ની કિંમત શોધો.
