$$\overset{{Hop}} {\Rightarrow}\:\underset{{x}\rightarrow\frac{\mathrm{3}\pi}{\mathrm{2}}} {\mathrm{lim}}\:\frac{\mathrm{2}+\left(\mathrm{1}+\mathrm{cot}\:^{\mathrm{2}} {x}\right)}{−\mathrm{sin}\:{x}+\frac{\mathrm{4}}{\mathrm{3}}\left(\mathrm{1}+\mathrm{tan}\:^{\mathrm{2}} \left(\frac{\mathrm{4}{x}}{\mathrm{3}}\right)\right)}=\frac{\mathrm{9}}{\mathrm{7}} \\ $$
