# Give the example of a function which cannot be integrated?

These are few examples of a function which cannot be integrated:

$\int \frac{Sinx}{x}dx\phantom{\rule{0ex}{0ex}}\int \frac{{\displaystyle 1}}{\mathrm{log}{\displaystyle x}}dx\phantom{\rule{0ex}{0ex}}\int \sqrt{S\mathrm{in}x}dx\phantom{\rule{0ex}{0ex}}Regards$
