Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

So regular i thought that the procedure was

F(s) = ∫^{s}_{0}f(x) dx

However i am doing a problem with a kinked pdf and it is telling me to do something like

F(s) = ∫^{s}_{0}f(s) ds for 0=<s>=1/2

then...

F(s) = F(1/2) + ∫^{s}_{1/2}f(s) ds

I am confused at the process of using f(x) or f(s) in the integral and the situation with kinked pdfs, if someone can shed some light on this i would be greatful.

Thanks,

Josh
