[math]\Delta[/math] is defined in >>11648231
Essentially, it's the identity relation.

>what's P(A)
Power set.
Absolutely weird fucking typo, tho, should have been [math]A^2[/math]. Apologies.
>>11651631
No, that's correct as is (with P(A) substitued by A^2, as mentioned just now).

f(n+1)-f(n) should depend only on [math]n ~ mod ~ 30 [/math], unless I'm going completely insane. This means it has a period, you can interpolate with an appropriate function and then take the integral for f(n).

Marry me.
>help this poor guy out
I would, but his question is a huge pain in the ass.
Like, you've got absolutely no idea how boring it is to wade through statistics notation and turn that thing back into analysis to check if that specific manipulation counts.
But it probably doesn't.
