જો $\mathop {\lim }\limits_{x \to a} \frac{{{a^x} - {x^a}}}{{{x^x} - {a^a}}} = - 1$ હોય,તો

ધારો કે $f: R \rightarrow R$ એ $x=0$ આગળ વિકલનીય છે. જો $f(0)=0$ અને $f'(0)=2$ હોય, તો $\lim _{x \rightarrow 0} \frac{1}{x} [f(x)+f(2 x)+f(3 x)+\ldots+f(2015 x)]$ ની કિંમત શોધો.

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.
