$\mathop {\lim }\limits_{x \to \pi /2} \frac{2x - \pi}{\cos x} = $

ધારો કે $f(x)$ એ $x = h$ આગળ વિકલનીય છે. તો $\lim_{x \to h} \frac{(x + h)f(x) - 2hf(h)}{x - h}$ ની કિંમત શોધો.

$\mathop {\lim }\limits_{x \to \pi /2} \tan x \log \sin x = $

ધારો કે $f(x) = x^{6} + 2x^{4} + x^{3} + 2x + 3$,$x \in R$. તો પ્રાકૃતિક સંખ્યા $n$ શોધો જેના માટે $\lim_{x \rightarrow 1} \frac{x^{n} f(1) - f(x)}{x - 1} = 44$ થાય.
