$$Astudentaskedmethisquestion$$$$Ianswered$$$$\mathit{l}\mathit{i}\mathit{m}\frac{0}{\mathrm{\infty }}=\mathit{l}\mathit{i}\mathit{m}0\times \mathit{l}\mathit{i}\mathit{m}\frac{1}{\mathrm{\infty }}=0\times 0=0$$$$\mathit{a}\mathit{l}\mathit{s}\mathit{o}\frac{\mathrm{\infty }}{0}=\mathrm{\infty }\times \frac{1}{0}=\mathrm{\infty }\times \mathrm{\infty }=\mathrm{\infty }$$$$\mathit{A}\mathit{m}\mathit{I}\mathit{r}\mathit{i}\mathit{g}\mathit{h}\mathit{t}???$$$$$$

$$example$$$$\underset{\mathit{x}\to \frac{\pi }{2}}{\mathit{l}\mathit{i}\mathit{m}}\frac{\mathit{t}\mathit{a}\mathit{n}\mathit{x}}{\mathit{x}-\frac{\mathit{\pi }}{2}}=\frac{\pm \mathrm{\infty }}{0}=\pm \mathrm{\infty }\times \mathrm{\infty }$$$$\stackrel{?}{=}\pm \mathrm{\infty }$$
