I am a little terrified at the moment as my Calc 2 teacher both mumbles and has a heavy accent. Anyways this is what caused me the most anxiety about the first class could someone please explain to me wtf he was trying to say by this?(adsbygoogle = window.adsbygoogle || []).push({});

these are two piece-wise functions

F(x)

1 x irrational

0 x rational

G(x)

0 x irrational

-1 x rational

and the integration of F(x)-G(x)=1 so um could someone please explain what he meant by x rational and x irrational.
