Let [math] \mathbb { Q } [/math] be the set of rational numbers, define: [eqn] f(x) = \cases { 1 \text { if } x \in \mathbb { Q } \\ 0 \text { if } x \notin \mathbb {Q} } [/eqn] Find [eqn] \int _{ [0,1] } f d \mu [/eqn]

What did he mean by this

he means he did a course on measure theory and now thinks he's hotter shit than wolfram fucking alpha

I don't know how good Wolfram is at integrating distributions, but I've taken enough Fourier and time-frequency analysis courses to probably know at least one such integral.
