lim = 0.1 => diverges
you could eliminate two of them because theyre clearly wrong i think the only one that looked right was if the integral diverges the series diverges but this is incorrect since they dont tell you the function is decreasing.
counterexample: sin^2(pix) + 1/x^2
the integral would diverge, but since sin(pi x) = 0 for all integers, the series would just be 1/n^2, which converges by p-series

guys im starting to think I screwed up on the EASIEST frq set cuz i made so many silly mistakes
For FRQ 6 part D, i got 10/9 cuz i thought it was asking for f'(1/10) instead of f"(-1/10)
For FRQ1, i got like max amount of ppl in the store as 17 cuz the derivative of E(t)-L(t) was strictly negative so i just used the the amount of people in the store at t=0 as the max amount, but ppl are saying its 65???? maybe calc error atp cuz idek where i went wrong
For the FRQ with partial decomp, i did all the work right but for some reason I put my lower bound as 1 instead of 0 (i knew it was zero btw) and got -6ln(2/3).
