comment Does there exist a sequence $\{a_n\}_{n\ge1}$ with $a_n < a_{n+1}+a_{n^2}$ such that $\sum_{n=1}^{\infty}a_n$ converges?
Do you have any example sequences that even converge to 0?

comment Probabilistic paradox: Making a scratch in a dice changes the probability?
So this last comment implies that there's nothing logically inconsistent about the first model, so the second model is taught because it is backed up empirically not because it's any better logically?

comment Simple probability problems
But why do 15 have a probability of 2/36? seems a bit circular to me...I imagine you'll say it's because 1,2 and 2,1 are different ways to obtain a pair with 1 and 2 in it but that implies order matters?

comment Derivative of a function is odd prove the function is even.
yeah i guess c depends on x i just got that from the mvt, trying to see how the result follows. c is the mysterious number between 0 and x, $f(x)-f(0)=f'(c)x$

f and g are both equal to $g'(c)x+g(0)$

comment Group of order 15 acting on a set of order 22
15,5 or 3 so must be 4 orbits of order 3 and 2 of order 5?

Well stabilizer is a subgroup of G right so 1,3,5 or 15, but if it was 15 then we would have a fixed point which we don't. So 1,3, or 5.
