ધારો કે $f(x) = \lim_{n \rightarrow \infty} \sum_{r=0}^n \left( \frac{2\tan(x/2^{r+1})}{1 - \tan^2(x/2^{r+1})} \right)$. તો $\lim_{x \rightarrow 0} \frac{e^x - e^{f(x)}}{x - f(x)}$ ની કિંમત . . . . . . . છે.

લક્ષની કિંમત શોધો: $\mathop {\text{Limit}}\limits_{x \to 4} \frac{(\cos \alpha)^x - (\sin \alpha)^x - \cos 2\alpha}{x - 4}$,જ્યાં $0 < \alpha < \frac{\pi}{2}$.

જો $f(9)=9$ અને $f^{\prime}(9)=4$ હોય,તો $\lim _{x \rightarrow 9} \frac{\sqrt{f(x)}-3}{\sqrt{x}-3} = $

જો $f$ એ ચુસ્ત રીતે વધતું વિધેય હોય,તો $\mathop {\lim }\limits_{x \to 0} \frac{{f({x^2}) - f(x)}}{{f(x) - f(0)}}$ ની કિંમત શોધો.
