Test if the limits exist and calculate them, if so.

a) ${\displaystyle{\lim_{x\rightarrow 2}\left(\frac{1}{2-x}-\frac{12}{8-x^3}\right)}}$ b) ${\displaystyle{\lim_{x\rightarrow -3}\,\, \frac{x^2-9}{2x^3+54}}}$ c) ${\displaystyle{\lim_{x\rightarrow 0} \, \left(\frac{1}{2}\right)^{\!\!-1/x^2}}}$

d) ${\displaystyle{\lim_{x\rightarrow \frac{\pi}{2}} \, \frac{\sin 2x}{\tan x}}}$ e) ${\displaystyle{\lim_{x\rightarrow\infty}\, \frac{\sqrt{x+1}-\sqrt{3x+2}}{\sqrt{x}}}}$
